I guess I answered to the same post into WA discussion. Here is a little reminder:
Ya, post a picture. Your solution shouldn't be to close the game, but MINIMIZE could be better. You won't loose your data.
BTW, people says "open an explorer window in Vista when your colors turn crazy". Latest news: isn't only for. I've Win2000 and when my colors turn crazy more then 3 times, I open and keep an explorer window opened and the colors aren't weird anymore.
If it happens to WWP too, as you said, it's more difficult to minimize, because you don't have the minimize button. I, ("happy

") Win2K user, can minimize it with Windows Task Manager. But you should be careful: don't crash the game! It's a super-hard technique to do with Windows Task Manager.
Edit: I was too lazy to rewrite "Windows Task Manager", so i abbreviated it with WTM. Now it looks like spam, so I put back the normal name. HAPPY EVERYONE????
