Panel Size

Greetings all,I am trying to "tweak" one of my panels, and am a little bit confused as to how the size of the panel bitmap is represented in flight sim. My panels appear to be stretched vertically from what my bitmap represents. For exapmle, I am running flight sim at 1280x1024 resolution and have a main panel centered on the bottom of the screen and an upper panel centered on the top of the screen. Together, the Y axes of the panels add up exactly to 1024, yet they do not meet in the middle of the screen when displayed in flight sim.Can anyone explain to my why this occurs and/or better yet how to get around it? Is the a "stretch factor" or something to take into account? Any help would be greatly appreciated.Regards :-wave,Chris BrunnerCYVR
