That's been posted before in one of those win 8 threads here, but I aint going looking for it ;-)
I'm starting to think that a lot of the problems people are having with windows 8 are bugs. I know I *keep* getting the charms bar popping up to the extent that it makes the OS unusable (presuming I want to stay sane as well). This doesnt seem to be happening to everyone, but it if it happens to me it's still a bug as far as I'm concerned. Maybe a lot of these problems are hardware/driver related. And the way all that 'stuff' interacts with the new gestures.
