I'm having a problem with my mouse (Details: Trackball,Dell Logitech brand ,ps/2 connected, Winxp. Dell computer 1year old). The problem is intermittent at worst so I decided to post here before I did anything. For the past couple of days after a few hours of activity my mouse pointer begins to jump up erratically to the top of the screen I can barely control it just enough to open other programs like the trouble shooter for the mouse. The problem usually stops after about 15 - 30 minutes. Sometimes the problem is shorter. System restore has done nothing to resolve the issue. A fully updated Norton Anti virus finds nothing after full system scan but, strangely when I open the troubleshooter for the mouse and try to open the task manager from one of the links in the troubleshooter Norton warns me that "script blocking has detected suspicious activity". Norton's log ends with the following FILE:HelpCtr.exe, OBJECT:File System Object, ACTIVITY: Get Special Folder. I was previously hijacked by cool web about a week ago but as far as I can tell cwshredder and a system restore cleaned that out pretty thoroughly. My logs on Hijack This, Adaware and Spybot don't appear to have changed since before the mouse problem. My background processes on Task Manager don't look suspicious. Is this strictly a hardware problem? Should I uninstall/reinstall the device driver for the mouse (I was planning on a new optical mouse anyway)? This is really an annoyance! Any help on either the hardware or software front would be appreciated...Thanks.
