Nah, still nothing.
thanks for trying for us, but I guess it can't be helped. maybe I'll try a full re-install.
EDIT: I reinstalled the game from the ground up and for three or four missions it was working again. comms menu was fine. Then in the middle of a flight not only did it vanish, but my esc menu moved into the upper left corner of my screen so I could only see a quarter of it. I can conclude that it's my resolution screwing up like Isegrim said, and moving my windows around the screen to places I can't see them. I AM running two monitors, so I fear that may be the issue, but disabling my extra monitor never fixed the comms menu problem the first time. Also, what would cause this to screw up in the middle of a flight?
This is a painfully stupid glitch/error/bug. I didn't pay for FC3 after putting it off this long only to have it raise this middle finger at me.
