What S.O. are you using? What version of DirectX have you installed? Do you know some graphic cards have an option to use 24 or 32 bits for million colors? Definitely is a graphic card issue, even if Poser doesn't use the card itself in no way (it uses system resource). I'm running Win2k with Poser 4.0.3, an ATI Rage IIc with 8 meg of RAM and latest drivers, DirectX 8 for Win2k (there are two versions, one for 2k and the other for 95/98/Me), and I NEVER had a problem in rendering. Try change the graphic card with another one (I suggest the Matrox G series, not a great one for 3D games but cheap and very useful and powerful for programs like Poser which doesn't use graphic hardware for 3D); if it doesn't work, you can try moving your card to another computer and test it. Another issue: is your system memory bad? As Poser uses system resource, even the system memory can be the bad thing...
