Well I have strange problem with my new AMD64 (3000+, winchester core)...Everything works fine and faster with Poser6-SR1 but the cloth room...I upgraded recently, and both my older and new simulations lock the software up when I try to calculate. Hair has no problems. Just the clothes. I tried both under WinXP SP2 and XP64... I had no problems prior to hardware upgrade. And all my other software (Lightwave 8, Photoshop CS2 vs.) runs perfect... Any ideas?
