Windows: Unlimited Mouse is a simple application that removes the mouse movement restrictions which keep your mouse cursor from breaking through the edges of the monitor. With it enabled, all edges wrap around to the opposite edge.
If you’d like to be able to whip the mouse towards the right edge and have the cursor come out on the left (instead of the just bumping against the right side), Unlimited Mouse is a good fit. It’s a very simple program; there are no customizable elements. Turn it on the the vertical and horizontal edges of your monitor no longer stop the mouse. Turn it off and the edges become hard barriers again.
One feature lacking in the application is the ability to toggle the vertical and horizontal sides. Many GUI elements are right at the top edge and the bottom edge of the screen and it’s easy to over shoot them if you have the mouse sensitivity cranked up.
Unlimited Mouse is freeware, Windows only.
