My Computer specs are: WinXP (SP2) Celeron 2.49 GhHz 248 RAM 70GB HD 1 CD/RW 1 HD No problems so far except Euro skin texture in Face Room splits map. Once had weird OpenGL rendering but installed new driver and now I am fine. I do not do huge renders though. I'm sure this doesn't make you happy Robo but computers are a mystery... something weird in your OS install? Something wrong in the production burning of your Poser disc? 2Gb Ram an issue? Gremlins? Sorry.
