No. The application has a different configuration (1400x1050) and does not offer 1680x1050 but it does not use this when it is running windowed. It uses the resolution of the containing window. When I change the application's configuration to various alternate settings nothing happens and the screen makes no attempt to resize. I doubt this is the problem, though, as I have tried setting my desktop resolution to the same resolution as the application configuration (both 1400x1050) and I still get the black bar at the bottom of the screen.
