Hi guys, Today I received my Pro Mouse that I bought used on ebay. It doesn't work. When plugged in, the red light on the bottom lights, but the curser doesnt move or click when I use the mouse. I have tried both USB ports and tried restarting my Powerbook, with no luck. I have a small USB travel mouse that works great, so I know it is not the computer, it must be the mouse. This is the model with the little wheel on the bottom of the mouse to change the button pressure, the one with 'Pro Mouse' and not just 'Mouse' written on the bottom. Does anyone know whats wrong or how to fix it? Thanks!
