a31p BT Intellimouse Explorer without dongle

[bmxsteffen]

hi there,

did any of you guys get the Microsoft Wireless Intellimouse Explorer Bluetooth (this one http://ecx.images-amazon.com/images/I/4 ... AA240_.jpg) to work on an a31p XP SP2 using the build in bluetooth stack and not the bluetooth dongle that comes with the mouse?
I manage to see the mouse in the BT-Environment, but when I try to connect a little window appears saying: establishing connection with mouse/keyboard but nothing else happens
with the dongle the mouse works just fine.
if I remove the dongle, switch on the build in BT and try to use the software which came with the mouse, it doesn´t seem to communicate with the BT hardware and doesn´t show anything in the BT environment.

any ideas?
many thnx in advance for any help!!
