I've had the Logitech cordless optical mouse for laptops for a good 6 months, and used it without problems. Now, after surfing for about 15 minsutes, the cursor clears off to the top RH corner of the monitor and behaves as if it is magnetically attached. After vilolenting moving the mouse in a circular motion, I regain control for a few minutes, then it dives to the bottom LH corner by Start. I have taken it to work, same O/S (XP Pro) and used it all day with no probs.I've uninstalled the software, I have tried another mouse USB connected, and still the same prob. I have Sophos AV which updates hourly, I have done a full scan, dscanned disk, defragged, just about everything.......still the problem. LOGITECH techos have never come across the problem. My computer is a Dell Latitude C 840, 1 GB RAM. Anyone out there who could help ?
If you have the same problem with your spare mouse then it could be either a software problem or a hardware problem with your machine, try antivirus software and antispy,maybe try a system restore dated before the problem started. hope this helps!
