Bluetooth hangs at shutdown/restart

Hi,

I have a D830 with Dell 360 bluetooth module. I have recently reinstalled pc with Win XP Pro. Now I get the error shown below every time I shut down or restart the PC. I have tried both the BT 2.1 driver and the older 2.0 driver, both with the same problem. I have not installed other software than Windows and a complete set of drivers.

Anyone have experiences this before and have a good solution how to get rid of this message.
