I desperately hope that someone can help me with this. Often when I am working with Poser 4 (PC) it will just crash, freeze, hang completely. It is so severe that I can't even reboot my computer, but have to physically turn it off and on with the switch.

This happens at seemingly random points.. during loading of figures, posing and positioning, or sometimes rendering. The mouse just stops moving, and the entire computer becomes totally unresponsive. Does anyone have any idea what causes this? What can I do about it? Any and all help is greatly appreciated, thanks very much..
