I'm trying to play the demo, but every time I fight a battle the game gets messed up. Once the battle ends and it is supposed to go to the "battle results screen" it gets messed up. It seems to have something to do with the loading and unloading of the different engines. Two times out of three the game showed the desktop, but still had the game mouse pointer and sound. The last time, the battle results window showed, but all other behavior was the same. When I click anywhere, the windows active mouse icon turns on, everything freezes up for a few seconds, and then nothing happens (back to the same point). So the game basically is totally frozen after any battle. If I ctlr-alt-del out to the process window I can watch the process fluctuation between "not responding" status (no music either), and running (music). It seems like its context switching, but I don't know why. Increasing priority has no effect either. No other application is running. Is this a VISTA 64 issue?
