Most likely an issue with the graphics driver. Either it hasn't been installed correctly/completely, or it is incompatible. The potential installation issue is discussed at http://www.clausbrod.de/CoCreateModeling/OsdmFaqGraphics#ProperInstallation . If the driver is incompatible, you can try disabling the parts of the driver which implement OpenGL hardware acceleration. This is done by setting an environment variable; details are available at http://www.clausbrod.de/Blog/DefinePrivatePublic20090715NiceAndSlow . Hope this helps, Claus
