I just installed panther, and now the eject, volume adjustment and mute keys on my apple pro keyboard have ceased to function. Nothing appears on screen when they are pressed, and they don't sound error messages when pressed in situations where they normally can't be pressed. I'm kind of disappointed that something like this could happen with the new OS. Hopefully its not a common problem (although, it'll probably be easier to fix if it is). The rest of my setup is a dual 1.25 G4 tower with an apple studio display. The keyboard is connected through a port on the monitor. Any help would be appreciated.
