I have two monitors. My primary monitor is a 1600x1200 display, and my secondary monitor is 1680x1050. When I drag windows to the secondary display, the windows maximize in the secondary display (as they should) but with the dimensions of 1600x1200 rather than 1680x1050. As a result, a gap appears on the right and some of the window is cropped on the bottom.
I'm running WinFX 3.0 but adding the app (iexplore.exe) to WinFX's exception list did not resolve the problem. Adding the app to WindowBlinds 5's exception list resolved the problem. Unfortunately, it only resolved the problem for that app; all apps that can be maximized seem to suffer the same plight.
