This was happening to me too.

Try switching to SreeD before a crash and see if this helps. <

SreeD? I'm not sure what you mean by that.

I also have the latest Nvidia drivers and Poser 7 update. What is working so far was to right click the Poser exe go to compatibility(sp)and switch it to Windows 98.

The only thing I don't procrastinate is procrastinating. That I do right away.
