--- Comment #1 from Dan Weiss danweiss@gmail.com --- I also tested GetWindowRect.
It returns the numbers that it is supposed to be returning, and claims that the window is 256x256 large, while the actual screen shows it at a full maximized size.
So now I'm confused to which component is messing up. Is it wine? Xorg? XFCE?
