I've searched this forum for the answer to my dilemma and came up dry. I hope this not a redundant post.In following the tutorial, I am at the stage where I have the overhead panel active, and have gone through the start procedure. At the point where I am to close the overhead using the "MZ..." interface, the overhead does not close immedately. I can call the FMC, throttles, but cant close the window.When attempting to close it by clicking the right mouse button and selecting "close window", the overhead does indeed close down....however, I lose the 2D panel, such that the bottom half of the screen is black.Was there a fix for this I missed?My video card is GFX 5600 with WHQL 45.23 nvidia drivers on XP. All else seems to be fine.Any help?Dom

Dom,Just click on "M", and the main panel will come back. "MZALO" are NOT toggles, unlike "TFR" which ARE toggles.- Bill Ruppel

With many thanks!RegardsDom
