I recently bought a new Kensington Slimtype keyboard for my PowerMac G4 (dual 867mhz); it's running Leopard and everything other than this is working beautifully. For some reason, whenever it goes to sleep, it turns the brightness down to it's lowest setting - not a huge problem, I just turn it back up. Just wondering if anyone else is having this problem and if they are, how did they rectify it?
