I have Vista 32 Home Premium. Dual processor. 4GB ram. Poser 8. No problems whatsoever (other than the known bugs)

I like Vista.

I just recently (after Poser 8, and just as a test) turned off the UAC. Never had any problems with UAC either, but then I'm using the Administrator account all the time.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
