Blue Soleil Bluetooth for Magic Mouse on Windows 7

Hello Apple friends,

I tried to connect my brand new Magic Mouse with my PC running Windows 7-32bit like it was recommended in this forum ( http://discussions.apple.com/thread.jspa?threadID=2221427&tstart=30).

Unfortunately, my Bluetooth dongle (MSI) uses the Blue Soleil software. When started, it recognizes my Mouse immediately. But right-clicking on "connect" does not work; Blue Soleil says "Authentification failed".

Does anyone have an idea how to solve this problem?
Thanks in advance!
