I have a couple of bluetooth headsets. One was paired with my Snow Leopard system before upgrade. After using it for audio output, now every time the system tries to make a sound, I get a dialog box saying "A Bluetooth audio error occured. There was an error connecting to your audio device. Make sure it is turned on and in range. The audio portion of the program you were using may have to be restarted." The button to dismiss the dialog says "Stop using headset". Regardless of how many times I click the button, and even if I reboot the machine, this dialog box seems to come back to haunt me whenever a sound is about to be made.
