My system is originally Windows2000 Pro. After a computer is boot, the mouse (photoelectric) will be jumped back and forth in the horizontal direction, and it will be repeated after a while. I feel that the mouse is a bit! I thought it was poisoned and killed! Rear system Windows XP Pro SP2. Replace the Machinery Mouse. The problem still exists! Who has encountered such a problem? The younger brother saved here! -------How to deal with it?
