The USB IBM laser Mouse on my XP machine is locked up when the computer is turned on. If I unplug it from the USB port and plug it back in, it works. This just started a couple of days ago and I can't figure out how to fix it. I've tried reloading drivers but that doesn't work. I used a different USB port and that didn't help. I checked for malware and the computer seems to be clean. Any ideas will be appreciated. Thanks. PS: I've also tried another USB mouse and get the same results.
