I have a MacBook Pro (2.4 GHz) running Leopard. I just got an external USB 10-key pad. The brandname is GFM (I can't find anything on this brand online). Granted, it was pretty cheap. When I plug it in, the num lock key on the pad lights up. I get a message saying that the computer can't set up the new keyboard that was just plugged in. To aid in this process, I should press and hold the key just to the right of the left shift key. Of course there is no shift key on my numeric keypad. Pushing other buttons doesn't work. Any ideas? Did I just buy a toy calculator for my 2 year old?
