Thanks for your input. Maybe you can ask them about the 8800 GT? I had the 7800 before that with the same issues. Like you, it freezes on response to those little windows coming up. Then a part of them stays on the screen when they should be gone. If I open my Task Manager, I then see part of that frozen on Poser's window also.
Recently, I got it up and running after cleaning out almost half my runtime. I also notice that it is only using half my dual-core processor, so it is maxing out one core and not touching the other. No wonder it's slow. It still goes to a gray screen (blank) when ever I ask it to do anything memory-intensive. My card has 512 memory on it. It should do better! Maybe only P7 can take advantage of dual core?

I am designing characters and it's not saving usuable Pose files, at least for the morphs, and Pose Inj Builder doesn't show most of the files I save with Poser. So wierd! I know someone with a Mac & Poser 7 that has no problems.
