When playing Elemental on a dual screen setup, in Windows 7 64 bit pro, when you click on the off the game screen to do anything on your secondary screen, it minimizes Elemental, which is good. When you go back to elemental though, it crashes with the DX Error. This doesn't happen on the startup screen (checked 4 times). Only when actually in the game play screens where it happens every time.
There was no memory dump to upload, the screen shot is very large due to dual monitors and is basically one big black screen with a popup box saying DX Error: Invalid Call. When you click OK, you are back to Windows.
Can upload a dxdiag if needed but, I imagine this error is common...
