CursorUS is a simple utility that allows you to navigate your desktop with continuous movement of the mouse, by extending it beyond the screen borders. This software allows your cursor to move continuously on reaching borders of the screen.

The effect works by transfering the pointer on the opposite side. There are many functions for partial blocking of the working effect. You can also set hot keys and extend the functionality using the "Options" dialog, which is available from taskbar icon's pop-up menu. CursorUS can also be used with a trackball.
