Why Does My Cursor Jump Around With Windows XP?
A cursor usually jumps around a computer screen when it has been improperly calibrated. To get the cursor to perform to your liking, you must recalibrate it.
Changing Cursor Animation
To adjust the animation of your cursor on a Windows XP computer, go to "Start" > "Control Panel" > "Printers and other Hardware." Click on "Mouse." Go to the "Pointer Options" tab and under the "Visibility" heading, change the settings to match your preference.
Changing Cursor Speed
In the same tab, you have to option to change the speed of your cursor. If the cursor is jumping around, try slowing down the pointer speed.
Always be sure that your mouse is properly plugged it. If you are operating a wireless mouse, jumping around may mean that your batteries are dying. Replace the batteries and turn your mouse back on. Your cursor should be back to normal.
