Yeah they contacted me and said the exact same thing as pennygod, the resolution thing works, kind of. I have narrowed the problem down to when I travel through the teleporters on hotseat/custom games. If I try the resolution thing hovered over where my teleported hero is, it does nothing. If I go back to areas previously explored, it goes back to normal, but as soon as I try scrolling over to my hero in the teleported area it goes black again. So if the screen just randomly goes black, can be easily fixed, but I can't seem to find any fix for the teleporters. Whatever, I can't really play as much anyway now, college started back up. I guess its for the best.
