Somehow, I've managed to render my "aircraft symbol" invisible? I am "in" an ADE which I've previously edited with no problem, and am placed appropriately on the airport. When I zoom in as far as I can, I still find the aircraft symbol invisible. What key command combination can I use to change the "size" of the aircraft symbol? Is there a setting somewhere I can change to make the symbol visible? When I tell ADE to "Center on Aircraft" it knows to move the display to what should be the proper location. If I press the "LOCK" button, ADE flashes an aircraft symbol over a blank section of ADE background. I'm certain that somehow I've entered an absurd combination of mouse "clicks" and/or keyboard presses to cause this. I just don't know where to look to find out how to fix it? I'm running 1.78.7298 (pro) with prepar3d v 4.5.
