Example Compiles but windows doesnt show anything

This happens to all the samples that I have tried under VS 2010. Anysuggestion?

Maybe Opengl Drivers issue?

Thanks In Advance

are you running windows natively? sometimes this problems appear when running windows on a virtual machine. It could also be related with your graphics card. which model is it?

Yes Im running windows natively.

The video card is a ati radeon xpress 200m
