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.

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

  2. aoleg says:

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

    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?

  4. Will says:


    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,

    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).

  6. aoleg says:


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

  7. Will says:


    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.

    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!

  9. Drew Wesley says:

    Hi aoleg,

    Do you have an update on including the Chrome compatibility code?

  10. Marcos says:

    Also want for chrome. Hope you have gotten to it.

  11. Pleeeeeeeessee? says:

    Pleeeeeeeese make this work with Google Chrome!! :(

  12. Cliff says:

    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.


  13. Cliff says:

    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.


  14. DRock says:

    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

  15. Richard says:

    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

  16. Azor says:

    Chrome plz plz plz

  17. JJ says:

    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.

  18. aoleg says:

    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.

  19. JJ says:

    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.

  20. pmshah says:

    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.

  21. ®ound says:

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


  22. DVDUFO says:

    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.

  23. aoleg says:

    DVDUFO: try this DLL http://www.mouseimp.com/downloads/MImpPRODll2010.zip

    It’s a pre-release version; if everything works OK, I’ll update the installer.

  24. aoleg says:

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

  25. Richard says:

    The new .dll did not work for horizontal scrolling in Firefox

  26. O-O ^.^ says:

    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)

  27. ppg says:

    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!

  28. ppg says:

    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.

  29. Chris says:


    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!

  30. O-O ^.^ says:

    Contains wininet has access to the Internet,Is spyware?

  31. aoleg says:

    O-O ^.^: Nope. Full source code is available anyway.

  32. O-O ^.^ says:

    aoleg : But I did not find the source code link.

  33. Alps says:


    Works well with VS 2010.

  34. guest says:

    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.

  35. guest says:

    The addons is for firefox, I miss it.
