If you're using the Logitech enhancements, you should probably remove them (Library folder?) and try again. The enhancements may be incompatible.Originally posted by Lz0
I don't know about all this.
I just upgraded to 10.2 and my Logitech mouse is tracking very slowley, I still have wheel and right button but the control panel doesn't detect a mouse. The same thing used to happen in all 10.x.x when I logged onto a different account without a restart.
