Just upgraded to tiger, and every time I boot up my mac the Keyboard Setup Assistant comes up, saying "Your keyboard cannot be identified and will not be usable until it is identified. To identify this keyboard click continue". I click continue, and it asks me to press the key immediately to the right of the shift key on the left side of the external keyboard (I'm using an iMac). I press the key, and it says I have pressed the key on my built in keyboard. I can quit this menu, but it comes up each time I reboot, which I'd like to stop.
