I started having a little mouse problem so I decided to download some new software and drivers for my optical mouse because I lost them on a reinstall. I had no problems until this flutter and erratic movement which we all know will eventually drive you batty. I am now trying to uncorrupt my system from that Wisetech software and drivers garbage. I should have known when the site disappeared and I had to pay to download drivers. My system even warned they were untested by MS and might cause immediate and future problems. Well I did anyway, and suddenly processes corrupted and although I quickly removed what I could, problems continue and my system restore couldn't go back to a pre- install checkpoint. Unless someone can help soon I will have to do a O/S (XP) reinstall because my system resources are now fighting to take over my CPU usage, with nothing running. This is like a virus and possibly could be since my firewall gave me an attack warning, but didn't identify it. I have run chkdsk/fix, a registry clean and restore with no positive result. I need supergeek, are you out there?
