Bill, > Are you plugging into your computer or through a hub (keyboard)? I haven't had > a single problem with mine, maybe you should try a software re-install? I plug it directly into one of the TiBook's USB ports, and I've tried on both of the TiBooks I've had recently. Several times during the day it will just stop working and only unplugging/plugging solves it. I've reinstalled the software and trashed prefs to no avail. Strange, huh? Bill
