I don't think it will help, but did youn by any chance, changed the hardware acceleration level of you graphic card ?
(Display properties / Advanced / Troubleshoot / Hardware acceleration slider)

I have to change it myself sometimes to keep compability with an old software gui, and forget sometimes to put it back to full acceleration.

>Another thing you can try is to go to Start/Run and type in dxdiag.exe - that will run the DirectX Diagnostic Tool. On it you can go to the Display tab and there will be a button for "Test Direct3D" - you can hit that to see if Direct3D is working on your system or not.


Dont be scared to UPGRADE the Direct X also. This page shows you the version you have. Shoud say at least 9c or something like that!

[EDIT]
Also if the reboot doesnt fix it and it was working a week ago, it could be a color depth or resolution setting. Did you change this? (New monitor, etc.) [EDIT]

Hi Michael, Thanks for the help. I am already running the latest drivers for my Quadro FX3400...I tried what you said and everything seemed fine on that score but then I read PaQ's comment and remembered that I throttled back the acceleration only a few days ago..so thank's PaQ im back working !!!

Thanks again guys
