DDMM prevents the mouse cursor from crossing from one display to another too quickly. It will allow you to lean your cursor against the screen border.
1 screen: you can lean your cursor against the screen border:
Will be updated with better screenshots and their descriptions in the future.

Just downloaded this old little tool of mine again and it is still working fine, even on windows 8.1! Even the "add shortcut in start menu" option pins the program in the Start screen. You can download the .zip file, extract it wherever you want (C:\Program files\DDMM\ for example) and run the .exe file. No one improved this program in the past 5 years but it is open source, if you need a change you can do it and request a sourceforge admin account for this project. A big thanks to jackr1 for his improvements years ago!

Looks like "shortly" is not very short, but it's finally here. Big thanks to my good friend Avi Werner. The brand new site is finally in the air, and it took only 1 evening (and part of the night, but who counts...) to make, or should I say, integrate from various ready-made sources with (quite) some work. Changelog posted on the site. VS2008 stands open on my laptop with tons of changes to be finished, but I can't find time for it. I will.

Seriously upgraded the application and released the files. Changelog included in the sources. Still didn't find the time to update this site, but will do that shortly.

Just finished this app and put it online (version 1.0b). I wrote this app in C# using .NET framework. Sources are available at sourceforge (not sure I released the correct files though). I tested this app on my 2 computers only. For a stupid reason I have to provide a dll along with the standalone exe, I'll have to find a way to fix that. I suppose GPU drivers will offer such a feature sooner or later, I just wrote this app because I couldn't find any good solution right now.
