Upgraded machine recently. A7 Wed/Med not working on new machine.

A6 on same machine works fine.

All A7 edit windows in Wed do not render anything-- all blank. No grid. Wed rendering setup is identical in A6 and A7 versions. Items appear in text scene tree, but not in edit windows.

Machine:
P4 Intel w/ Windows XP Pro Sp3
Still haven't installed a video card-- using motherboard video output for now. I'm hoping a new card will fix it?

Updated Direct Drivers to latest.
Updated GPU Drivers to latest.
Still 3D edit windows do not render.

Strange that A6 works but A7 does not...
Any help appreciated.
