2D Panel Doesn't Display - Black Box Only

Hi,I just set up my new computer and after reinstalling FS9 I have run into a major issue, that I can't seem to resolve:Instead of displaying the 2D panel my sim only displays a black rectangle covering the entire lower half of the screen. The 3D panel and all other views work fine. This occurs regardless of the panel/aircraft.I am suspecting that this may be an issue related to the graphics card, since the 2D panel does show up properly for a second or so, after hitting the alt key to bring up the FS menu bar. Maybe it is related to the resolution I'm driving (2560 x 1440)...I was wondering if someone else has encountered a similar issue? Any hints would be greatly appreciated!Specs:FS9.1Win 7 x64 Proi7-860Ati Radeon Mobility 485027" 2560 x 1440 LCD
