My "C" drive is system managed. Poser 5 is on my "G" drive and I have this set at 3Gig on "initial size" and "max size" and to page file. I too am running XP with 512 RAM. Since upping my VM to 3 gig I've had no more problems. The memory usage is also set for "programs" not "system cache" and the "processor scheduling" is also set for "programs" and not "background tasks"

Injustice will be avenged.
