I have to agree with dlk30341's disagreement. Although I only have minor problems under WinXP64, I still need to keep V6I and P7 running on my 32bit system (just to run SkinVue), and the 32bit setup is very limited.... 2, maybe 3, Poser figures and it's down (and that's in otherwise empty scenes). I also have confidence that it'll be worked out eventually... I remember V5I taking several months before it could handle large loads.
