I have had nothing but headaches trying to use Bluetooth mice with PowerBooks. The symptom is that the connections are very intermittent. I could be in the middle of using my mouse and it would loose connection. Most of the time it would reconnect after a few seconds. I've tried three different brands of Bluetooth mice from low cost to expensive and even a couple of different PowerBooks. The mice have all had fresh batteries and the PowerBooks using the latest software updates for Panther (v10.3.9). I would love to use a wireless mouse but this is just driving me crazy! 
Anyone have a solution?
