Hi, I'm a noob to the board and Macs. I recently purchased a Logitech Marble Mouse. When I first plugged it in it worked, then I installed the mouseware software and it stopped working (freezes). I called Logitech support and they didn't help me at all. I reboot my power mac G4 and if the mouse is plugged into the USB port the computer won't boot up. I have to unplug it for the computer to boot. I tried uninstalling the mouseware drivers and I still have the same issue. I'm running OS 9.2.2 and I'm using Protools. Any advice? Thanx.
