Thanks David.  IT seems to be just that machine.  I copied to a different
system, and it worked.  from msdn, there's only one error code,
D3DERR_INVALIDCALL, and fortunately (or not), that's what's coming back.
The screen is 1280x720 via DVI.  I loaded up dxdiag, and ran the tests, and
they ran fine.  The d3d9.dll version is 5.03.2600.5512, the same as on the
other two systems.  The size being passed to CreateOffscreenPlainSurface is
720x400 (the size of the video), so it shouldn't be an overall window size.

I see two main differences.  One is that it's DVI rather than standard VGA.
The other is that it's a VIA chipset rather than a straight Intel. Not sure
why either of those would make a difference, since the regular D3D tests
