My multi monitor setup works fine. Currently running 1x 8800GTX power 1 22" LCD Monitor and 1 42" LCD TV and second 8500GT running the third 22" LCD Monitor. Using the lastest 181 nvidia drivers. I recommend updated your video drivers.
I installed the Toshiba bluetooth stack for Vista x64 on my Win7 and it works perfectly. All my profiles works fine. Toshiba Europe GmbH Bluetooth Information Center Its a 30-day trial but you can find the full version if you look hard enough. ;) Hope it helps!
