I was having some problems with Poser5 when someone told me about the service packs and upgrades for Windows at the Microsoft site. I downloaded SP1 for WinXP along with a few others, and between that and SP1 for P5, I dont seem to be having any problems at all now! I am wondering how many of our stability issues are from Windows problems. I have been advised NOT to us the driver updates from MS, as they may not be the latest...go to the OEM site instead. Hope this helps someone. Scarab
