Sometimes after landing, I press Cntrl+Q, then Enter and it will exit the game completely. Other times it will take me to a debrief, which is preferred of course.
Any ideas ? I did do some research before asking, but found no answer.

You gotta be crazy, you gotta have a real need
You gotta sleep on your toes, and when you're on the street
You gotta be able to pick out the easy meat with your eyes closed
And then moving in silently, down wind and out of sight
You gotta strike when the moment is right without thinking
