In FSX, interactive elements may lose their clickspots in certain light conditions (dusk or dawn). Switching on the panel lights usually helps. Worth a shot?
Thanks for the tip.
Tried that but doesn't help .....
Besides, this wouldn't explain why the clickspot visibility depends on the exact eyepoint position in this case.
In any light condition, shifting the eyepoint left and right a bit will hide resp. show the clickspots.
As a sidenote: the zoomfactor, or small fore/aft movement of the eyepoint, has no influence as well.
