Max5.1 SP1 viewport problem

[TechSmith]

I just got an FX 5700 so I updated max 5.1 to SP1 tp take advantage of the DX9 features. Now, for some reason all meshes are showing up as white. I can assign a material to the mesh and it stsys white. Yes, I've clicked the show in viewport option in the material editor, but still no luck. anyone else here run into this?

Hmm. Never seen that happen before. What is your Viewport Renderer set to (in Customize -> Preferences)... DirectX?
'Fraid I can't help you on this one... weird.

Thanks MoP, I tried switching back to Open GL and everything works fine again. Strangest thing I've ever seen in DX mode.
