Flew for a couple of hours -- no problems -- then dumped to the arena menu. Could still hear engine noise, tried to click on the arena but mouse just fired guns. Alt-f4 to escape.
this has happened to me 3 times, once in ww1 yesterday..another time yesterday and once today with new load..
i could hear coms and game..
I pressed windows key on keyboard
then AH game icon and I was back in game ..still flying..
try that if it happens again..but there is a bug for sure
