My Microsoft Optical Trackball mouse cursor is skipping, what can I do?
If you are experiencing the mouse cursor skipping issue with this mouse, the first thing you will want to check is that all of your mouse drivers are up to date.
The second thing to check is to see how your mouse is connected to your PC. A known solution has been to not use the USB connection for this mouse, and to hook the mouse up via the PS/2 connection.
