If I alt+tab out of the game and then try to go back into the game I get the "DX Error: Invalid call" message in the image below. No zip file was generated in the ProgramData folder. http://dl.dropbox.com/u/4314973/Elemental%20alttab%20crash.png http://dl.dropbox.com/u/4314973/DxDiag.txt http://dl.dropbox.com/u/4314973/debug.err

Forgive me if this has been suggested elsewhere, but another option if you are going to go that route is to have enchantments reduce your mana regen rate.
