Bluetooth EV3 connection problem on Windows XP

[donttell]

Hi,
I am using the EV3 SW on my notebook with Windows XP. When pressing the refresh button for connection there is no result.
When opening the BT environment from Windows XP menu then I am able to establish a serial connection to EV3 brick. But the EV3 SW is still unable to see the EV3 brick.

I cross checked with a desktop PC running Windows 7. There the BT connection works.

I would prefer using the notebook with Windows XP and wonder what is wrong here?
Has anyone similar problems?

PS: The EV3 is my first Mindstorms.

Solved.
Uninstalling the BT driver on my notebook and installing Microsoft BT stack helps.
So it seems that EV3 SW does not support BT stack other than Microsoft BT stack.
