I have this weird behaviour: In any aircraft I open a panel e.g. radio and undock it so I can move it on a second monitor. It has worked without problem.
For a few days now when I undock a panel it will show a copy of the main view and the actual panel graphics disappear! Even menu access and mouse panning is also shown in my panel window.
This happens in 2D view and VC. I have no clue how I did this. So far I have deleted my fsx.cfg for a fresh start but it didn't help.
What can I do?
