My mouse pointer creates a trailing effect when I move it

Cause: Your mouse pointer can be configured to trail when it is moved, which just gives it a blurring movement effect. Some people like this; others get a feeling of motion sickness. If you don’t like it, you can easily stop the behavior.

 You might not be a Keyboard Ninja, but would like to be able to navigate through Windows with the mouse more quickly. You can make mouse navigation faster by increasing the pointer speed and using the “Snap To” option  available in XP, Vista, and Windows 7.
