This leads me to suspect a problem in either the kernel or the desktop, but I think I've tried restarting the gdm before for this with no luck (had to reboot), so I more strongly suspect the kernel (driver/s). The mouse works just fine in both cases. It's an EX110 wireless desktop, BTW. My son uses the exact same hardware on his Windows machine, and it never does this. In fact, the first time this happened, Logitech sent me a whole new wireless set, and that's the one I've been using ever since, and this has happened before a couple of times. Once it just went away by itself, the other time I deliberately rebooted to fix it. I should probably point out that I use the PS2 ports instead of the (optional) USB connection - does anyone know if that works better (I suspect it might, since the USB drivers seem to be more robust than most). Rebooting is not a good solution, even if it works as a "fix." mhr
