I have a client who is having the strangest problem with her PC. In applications such as Excel, GroupWise, and even Mozilla/IE, her computer is automatically scrolling. When I first saw the problem, it seemed to me to be a stuck PageDown key, but after I swapped her keyboard for a working one, it continued to happen... I have also switched mice. We have reinstalled drivers for both mouse and keyboard. Her computer is running Windows XP and it is fully up-to-date. Virus and Spyware scans are also coming back negative. Has anyone out there seen this before?
