Yesterday. I had a strange thing happen.

I loaded a saved B-52 Cold-N-Dark flight. The widows were open and I couldn't close them. I decided not to worry about it and continued on. A little later, I had taken off and was climbing through 5000' (roughly) when I tried to close the windows again. It worked. I might have been able to close them earlier, but because I had decided not to worry about it, I hadn't tried again.

The only other time I couldn't close the windows was in multiplayer.
