Mine works, but only partially. About 70% of it is fine, but if I render, I have to wait for over a minute for the render dialog to go away after the render is finished. The same thing if I delete anything, or if I parent anything, or I conform anything or change the texture in the material room. I've heard that I need to update my ATI drivers, but I have several times and I still have the same problem. I know others do to. Somebody bought Poser Pro and he still had the same problems with it.
