We have covered on how to set up dual display set up in Windows 7 previously on this blog. Now when you are using dual display or more than one display, there is a chance that mouse might get jumped too easily from one monitor to another. DDMM (Dual Display Mouse Manager) is a program made for people who use dual display (several monitors). It prevents the mouse from crossing from one screen to another too easily.
The application does not require any installation and runs from the system tray. It can auto detect both the displays or you can specify the displays using the screen boundaries option in the tool. This app needs .Net framework installed.
