What is MouseImp?

MouseImp PRO is a successor of MouseImp that became popular all over the world. Many users’ wishes were considered in this new version of MouseImp, and many improvements have been implemented, making it even faster and more reliable. Hope you’ll like it, and its unique features will make your work easier and more productive.

Update: a 64-bit version is on the way…

MouseImp is a handy tool that helps you to use your conventional mouse more efficiently. The AutoShrink feature increases your available workspace by removing toolbars from the screen so that only caption bars remain. To access a toolbar, just point to its caption, and it will be restored immediately. The Direct Scroll feature makes it easier to scroll through windows. Instead of using a scroll bar, you can activate MouseImp and scroll by moving the mouse up or down anywhere in the window.

MouseImp also gives you the ability to shrink windows temporarily.

  1. Actually, it DOES work in FireFox. Try getting the latest version of MouseImp Pro Live!, and, if it does not do the job in FireFox, update it with “MouseImp Pro DLL” download. Note: you might have to restart your computer after that.

  2. I installed latest MouseImp PRO Live! and newest DLL.
    Vertical scrolling in Firefox is working now, but not horizontal �

  3. Yes, horizontal scrolling doesn’t work in FireFox. Volunteer developers are urgently needed 🙂

  4. This lovely utility has been with me since the down of time – thanks for bringing it back to life 🙂

  5. Greetings, I LOVE MOUSEIMP!! loved it since the first version.

    However, when using “WINDOWBLINDS”, the scrollbar direction is reversed, regardless of the ‘inverted’ option in mouseimp.

  6. It seems to be a great tool, but the horizontal scrolling does not work in opera. �

  7. elfranche,

    I believe, the scroll can be made in both directions by enabling the Options – Directscroll – Bidirectional feature.

  8. Did you get the updated “MouseImp Pro DLL” from the download section? It actually solves the problem (you might need to restart Windows in order for MouseImp to start using this DLL instead of the original one).

  9. I mean, simultanously!! Such that I can scroll diagonally… this would essentially make the mouse control the entire window’s background. superb for scrolling over large photos!

  10. Hi,

    Does it work only on Internet Explorer, where can I see the system requirements of the tool please?

    I tried searching in the Firefox extension, to download it from there too.


  11. I also use mouseImp and windowblinds. Ever since version 3.4 (i think) mouseimp and windowblinds began having conflicts. I really love both programs and if i knew how to fix it myself, i’d paste a plugin or some other sort of solution. Still i’d like to ask you guys for some guidance on this subject. The problem is that instead of “dragging” the screen with mouseimp, it seems like the scrollbars follow the mouse movement. If one is on the middle of the screen and begins dragging from the top, the scrollbar goes immediately to the top and follows the mouse movement, with very dissorienting results. If i turn off windowblinds mouseImp works just fine. can you guys please help me?

  12. Anyone know how to use a 4th mouse button with this. It only supports the Left/Right/Middle. Any options to pick a different button?

  13. Great tool.
    I’m using it since end of 1999 (7 years).
    Thanks a lot for bringing it back.
    Releasing it as open souce gave the immortality to this nice utility.

  14. Hi, I just installed Vista and FIRST software I tried to install was MouseImp Pro. Really !!! I can’t imagine windows without this feature. MouseImpPro doesn’t work (actually it works, but most of new opened windows/applications fails).. so I started to search on web and I found this page. It’s great that MouseImp is not dead ! I’ll try MouseImp Pro Live today evening on Vista, but I don’t think it will run… will see.

  15. So the result is that MouseImp Pro Live works in Vista, but it also can’t be running because other applications are very unstable and often fails during start �

  16. If I had money, I would order a computer programer for develeping and improving this realy useful soft… but now it is only one hope to volunteers…

  17. Once again PLEASE! make it scroll in both directions SIMULTANEOUSLY! it would essentially behave like a ball mouse, i.e. in all directions, but whilst controlling the scrollbars.

  18. Hello,
    I can confirm that mouseimp pro does not work properly with Windows Vista. Is there a plan to make it compatible with Vista? I very much like this software and hope a way will be found to update it.

  19. I am yet to install Windows Vista. I will surely try to do what is possible to make MouseImp work with it, but no guarantees…

  20. there is still a conflict with mouseimp and a installed 3dconnexion-spacenavigator.
    need that device in some 3d-applications and do not want to miss mouseimp – could you fix that.

  21. What’s the conflict with 3dconnexion-spacenavigator? Does MouseImp cause it to crash? If so, did you try the latest build that supports Vista and Office 2007, that solves a number of compatibility problems?

  22. MouseImp!! this software is very good
    I’m using tablet..so I have problem with scrolling..
    but finally, I got MousImp.. It’s over!

  23. Thanks so much for keeping mouse-imp alive – I use a Wacom tablet and it’s crucial for web browsing and other scroll intensive tasks where a mousewheel would otherwise be used. If you guys own the patent on drag scrolling, you should sell it to Wacom!

  24. Started using it since the times when mice did not have scrolling wheels. But even with a scroll wheel this app saves me lots of time.

    BTW, in case anyone did not know – if your mouse has a scroll wheel, *clicking* the wheel will turn on auto-scrolling mode in most apps, such as Opera, Firefox, IE, MSWord, Excel, OpenOffice, Windows Explorer, Konqueror. For Firefox on Linux you first need to enable ‘automatic scroll’ which is off by default.

  25. I’d used the old mouseimp, now using mouseimppro with gratitude!

    Any hope to make it work with Google’s new Chrome browser ?


  26. 10000 Thanks for keeping the great tool alive !

    And please, please, try to make it interoperate with Chrome !

    I pinged the Chrome developpers about this question, they answered back it has to be done by Mouseimp Pro.



  27. Chrome support is on the way. I have the code already, just need to implement it and upload the installation file. May take me a week or two though.

  28. Great!!! I was looking for it from a long time…
    any chanche to get more Activate on keys or combination for scrolling?
    I use a wacom tablet and I like to have some Control + Alt or some more complex combination because left middle e right button are already used for other.

  29. As soon as I get a 64-bit compiler, I’ll try building a 64-bit executable. No guarantee though as the source code is well dated, and can be only assembled in full under Visual Studio 6 that does not have 64-bit support.

  30. Hi and thanks for the neat application. Anyways, here’s my two cents on how to improve and enhance the direct scroll feature: (all from the perspective of a Vista tablet-pc / touch screen user)

    1) User could customize which programs were to use the scrolling feature. For example, you could disable the scroll feature entirely in Firefox because you already have a Firefox specific scrolling add-on which you’d like to still use (currently using Grab and Drag add-on to control Firefox and MouseImp on all other windows causes the Firefox add-on to act strangely). Or if there are certain applications where there’s simply no use for the feature.

    2) User could have more customized ways to enable and disable the scrolling feature. For example to briefly disable the scroll you could double click text area in any program or window. Also, the user could specify any of the keyboard buttons or key combinations to enable and disable the direct scroll. Having that feature would allow the user to map scroll disabling/enabling to unused media buttons etc.

  31. I think mouseimp has its problems with the webkit engine. For me it is not working in safari too. Both chrome and safari uses webkit engine. Very nice utility though. It saves a lot of stress while scrolling.

  32. Gusto, thanks a lot for your suggestions! I was thinking about disabling MouseImp scrolling in FireFox automatically if Grab&Drag is activated, but currently cannot find out how to detect one running. Having a list of appliations where MouseImp should not be active is another option, though.

  33. Unfortunately, MouseImp doesn’t work with Office 2007 � I only tested if on Word and Outlook 2007, so I assume it won’t work in the others as well �

  34. It does. English versions of Word 2007 is fully supported, while Outlook 2007 should work, too. However, it’s vertical scrolling only, and I haven’t done any testing on any international versions of Office 2007 apps. Also, 64-bit platforms are not yet supported (I am not sure whether or not it’s even possible).

  35. Hmmn, that’s interesting. I’m running Windows XP, SP3 (32bit)
    MouseImp PRO Live!
    based on MouseImp PRO v

    I’m also using the dll for Mozilla.

    I’m running Microsoft Office Word 2007, English version

    MouseImp works for everything else and only stopped working in Word 2007. It previously worked in all of Office 2003.

    Any suggestions? I did a clean install on this computer and I haven’t downloaded any versions of MouseGimp for over a year as it hasn’t changed has it?

  36. No need to use a separate DLL. The current MouseIMP distributive has the latest DLL with Office 2007, Mozilla and Opera support. Try reinstalling MouseIMP (and re-booting the computer afterwards).

  37. Ok, just downloaded and reinstalled it and now it works as expected in everything but the Inbox view of Outlook 2007. For example, it works while reading emails in Outlook, it works in Word 2008 it just doesn’t work when trying to scroll down the inbox window view. The mouse pointer turns into the circle with a cross through it when you right click and drag.

    Would it be possible to update the download section mentioning that you don’t need to do the dll separately now?

    Love your work!

    Thanks heaps!

  38. Hello! After upgrading to IE8 I noticed that Mouseimp Pro no longer works. Any chance we’ll see an update to support IE8?

  39. You need to restart your computer one more time, and MouseImp will catch up with IE8 (I just checked it myself, it works).

  40. Hi aoleg,

    Have you implemented the Chrome code in the wonderful should-be-installed-on-all-pcs MouseImp Pro Live! utility. This would mark a checkpoint in PC history, helping what is becoming the fastest browser now available.

    Have you considered contacting Microsoft so this can be a built-in feature in future Windows versions?

  41. Hi,

    I love it, I’ve only found about this tool yesterday, I’ve been using MouseStar from MagicUtil (not free) for the past 3 or more years but I got sick of it because of the lack of support for Visual Studio .NET. IE8 works great as well.

    I have a question, I download VS C++ 6.0 SP5 and tried to build the program, the code does not compile right away, there are files that are missing, first of all the icons were missing from previous projects but that’s ok cuz I got a copy of them However, there are at least 2 other files that I don’t have:-

    #include “resMImpCfg.rc2”
    #include “..helpMIPROHLP.H”

    Please let me know if I am missing something, it would be good to get this compiling because I’d like to make some changes to it.

    Please email me if you need to.

    Kind Regards,



  42. Unfortunately, I don’t have those files. What you see is the way the project was when I took over it. However, good news is that you probably don’t need those files, as the only thing necessary to re-compile is MIPRO.DLL, which you can do even without the mentioned files, and even in VS.NET 2005 (that’s what I use).

  43. Drew,

    I have the necessary code for supporting Chrome, but no time on my hands to implement it. Hopefully, in a few weeks…

  44. Hi,

    Thanks for reply.

    I would have like to change the main icon MImpCfg.ico which is part of the MImpCfg project that I can’t compile because of the missing files.

    I know I could use resource hacker / tunner to do this, but it would have been better if I could compile it.

    if you happen to get those files sometime in the future, please add them to the project. I am sure others will want those missing files for other reasons as well.




  45. I recently got a new laptop at work running Windows XP with Office 2007. I really like MouseImp so am very disappointed it does not work as well in Office 2007 as it does in Office 2003. I can vertically scroll in Excel but not horizontally. In Outlook, the vertical scroll works within a message but not in the Inbox view of messages. Is there any plan to correct this? Thanks in advance for your efforts!

  46. I have a couple of feature requests for DirectScroll:

    1. Add an option to lock the mouse pointer position while scrolling. So, while I’m dragging up or down to scroll, the mouse pointer remains fixed in place.

    2. Add an option for scrolling to affect the window under the mouse pointer, rather than the window that has focus.


  47. To clarify my feature request #2, I meant the scrolling would affect the window under the mouse pointer, without giving it focus. So, whatever window had focus before scrolling, keeps its focus.


  48. Feature request: If possible I would like to see the option to set activation to both mouse buttons. Having it set on right or left click interferes with these normal functions. Plus my mouse doesn’t have a middle button

  49. For horizontal scrolling in firefox I use ” Grag and Drag ”
    It is set to use the left mouse button and only on non text
    areas, This allows horizontal scrolling while still allowing
    the text highlight function.

    It is a workaround but is better than nothing.

    I have used mouseimp since before it was freeware and
    cannot live without it.

    BTW: it will work on Windows 7 x86 (32 bit )but not on Windows 7 x64 ( 64 bit )

    Note to Mazola: Please fix Firefox to work properly! with

  50. I finally found a free alternative to Mouseimp for Windows that works with google Chrome and doesn’t crash in Vista 32 bit.

    Mouseimp kept causing weird crashes on applications on my Vista 32bit machine. I didn’t have it running, then as soon as I started it up applications would start to crash.

    I was also frustrated that Mouseimp wouldn’t work with google Chrome.

    I just got a Logitech Trackman mouse for Christmas and accidentally stumbled across “Marble Scroll”. Even though it was primarily written for the Logitech Marble Mouse, it works great with my Trackman and I also tested it with a regular mouse.


    No more crashing apps and it works with google Chrome.

  51. I’ll make a topic for this program as well!

    EDIT: nope, that’s not *it*. Unfortunately, MarbleMouse works in quite a different way, and is no replacement for MouseImp or the paid alternatives.

  52. Perhaps we use it differently. I’ve only used MouseImp for a middle mouse button grab/scroll. This is exactly what Marble Mouse does for me.

    Perhaps it’s because Marble Mouse doesn’t support right/left mouse button drag/scroll, which is fine for me because I use the right for gestures and the left for QuickDrag functions.

  53. I can confirm that MIMP works on Win 7 Ultimate it creates a lot of other problems and that the explorer keeps crashing. At least that is the only solution I found – uninstall it in safe mode!

    I just wish and pray that someone would come up with a compatible version. I am so used to it! Without it I am practically miserable.

  54. Does anyone know any ALTERNATIVE tool?
    Because, latest (on current data) downloaded version of MouseImp still does not work under Windows 7.


  55. Hi,
    First thank you so much for your really good software.
    MouseIMP really speeds up my works in computer.
    But unfortunately MouseIMP don`t support Opera 10.51 version and Google Chrome. So I decide install old version of Opera witch is my favour web browser. I will wait for new version of MouseIMP.

  56. BTW, the new DLL is reported to work on Windows 7 32-bit. It also adds support for Chrome and Visual Studio 2010.

  57. Hi,
    thank you for your software. too

    both Opera 10.51, Chrome works fine, on Windows 7 32-bit

    Can U add the support of MS Office2010 (OneNote2010, Voiso2010, Project2010)

  58. Installed the new dll. Works super fine in Visual Studio 2010 on Windows XP 32bit, but not in Office 2007. If it works in Office 2010 I’ll be satisfied with that 🙂
    This is one of the essential utilities I cannot live without actually. Really appreciate your work and continous support!

  59. Sorry for being unspecific regarding Office 2007. It seems to work fine in Word and Excel, but in Outlook I can’t scroll the message list, but the mail windows works fine.

  60. Hey,

    is this program still being developed? Will there be a new version where some of the feature requests (disable scrolling for specific programs)?

    I really like it!

  61. It’s fine if mouseimp implement an exluded program list or individual settings for programs.
    I don’t want mouseimp to works with some programs, and there is no way to do this.
    For example, I use an addon called Grab and Drag to instead of mouseimp, and free the right mouse button to work with another addon which called FireGestures. But now I can’t do this when mouseimp is running.
