Technical FAQ - OSx86: "Q: Why don't Chess and the DVD Player work? I only see a grey screen.

A:Both Chess & Preview (& Grapher 3d) rely on OpenGL to draw their views. This can be modified for Preview by editing com.apple.Preview.plist in your preferences folder. If you have an intel extreme graphics board and got OpenGL / Quartz Extreme to work, all these apps work right."
