Recently a couple of XP SPK 2 computers in my office started to display a strange creeping movement of the mouse cursor. At times the cursor will begin to move up and to the right until you grab hold of the mouse. At first I thought it might be some dort of vibration in the office causeing the mouse track ball to move. I changed out the mouse and it still happens. Upon researching this, many say it is caused by Logitch mice. This didn't sound "logical" and I did manage to find one article relating to some sort of virus. I went to the top 3 virus protection sites but could not find any mention of a mouse moving virus. Any help on this would be greatly appreciated.
