Hitting 'escape' in a station got me to the options menu, which is ok...
After hitting escape again, I saw a black screen, with only the chat interface open. Chatting was possible, but only logoff could resolve the situation.
Happened twice within a short while.

I got it too, after toshiro talked me into trying it...
Only I didn't see the black screen, but the station in the background. Here's the pic:

Seems to happen every time you ESC instation. If you use the buttons (options, close, etc.) it doesn't happen, at least not with me.

Oh. I have the station backdrop off, since it hogs fps in-station.
