I had this problem last year, and today it's returned. During combat (perhaps because there's a lot more activity?), the screen will go completely black, but I can still hear the game, and my skills and weapons still work (except I have to continue using them blindly, just guessing where the cursors will be). Fortunately, it never lasts more than about 5 seconds, but it's annoying and ruins the enjoyment a bit.
Have any of you seen this problem, and is there any reliable fix or workaround? I'm guessing it *may* be graphics driver related.
