Further information on this problem...If I use the mini map altitude slider to go to 35000 ft, then the cockpit does not turn dark (the problem doesn't happen). The problem only happens when I take off normally and happens with each flight. When this does happen, everything outside the aircraft looks normal. The controls still work. But a view of the cabin is also completely dark.
Are any other x-plane pilots experiencing this besides Captron? It is very frustrating!! If someone has already submitted a bug report, please let us know. If not, I will try to put one together...Captron, please let me if you have anything to add to your description of the problem.
