I couldn't figure out how to word it but the point is that ZQ crashes immediately if one side of its resolution is equal to the same side of the screen resolution it's in.
i.e. the new interface, which is 800x600, crashes immediately on my netbook's screen of 1024x600.
Then again it might be my s*** netbook's god-awful drivers that are the culprit but if someone could just try firing up ZQuest and ZC in windowed mode with either side of the window being the same resolution as the screen's to see, please do.
