Probably [0.262][Crash] going back to Elmental after minimizing

I minimized Elemental using ALT-TAB to look at some forum posts here, and when I clicked on the Elemental window Elemental came back up but the window was all black and my computer froze.  The music from Elemental continued playing, but I couldn't see my mouse cursor or click on anything.  I'll post links to the debug.err, the dxdiag and the memory dump in the message body and the links section.
