shame on logitech trying to stop us from using r webcam. so we go and buy a new on from them. well im never buying from them again after i found out that they wrote the files to stop it working on vista. good job they didnt do a good job of that changing a few codes do they think in the age of the internet that would make us go and buy a new webcam.

well few days of googling and one more vista problem solved.
