I'm running PP2010 on Windows 7 and it works fine--but I didnt allow IE to upgrade, so maybe that is why. I also got the new PP21010 service release, but havent launched it yet, and I understand (perhaps wrongly) that it will allow Poser to work with the new IE version. I'll try it one of these days...
