sturkwurk:
Are you also running Windows 7 (32 OR 64 bit)?
What version of the NVidia driver are you using?

softcris:
Are you saying that when the freeze in Poser 8 happens, your computer's memory usage increases (in other words, your computer system slows down)? Because my computer DOESNT suddenly use a bunch of RAM... Poser 8 just stops working, while the RAM usage remains at a minimum.

I am also talking to Smith Micro about his, and they are blaming my NVidia driver upgrade or my Poser 8 preferences.
I told them before they responded, that deleting the preferences doesnt fix the problem for me and that I had updated the driver BECAUSE of the problem.  I am foreseeing a whole BUNCH of emails back and forth on this issue.  :(
