Hi, 
  
watching the preview for the next phase to come (wow, wow and wow!) made me install OFF again and buying HitR. 
I am now trying to play it in earnest. However, in a campaign I experience a sudden return to the flight menu (the one before the briefing room) and my flight is usually not recognized.  
It seems to turn up occasionally, since I almost managed to finish one flight and the crash came close to my touchdown, thereafter my flight time was recognized. 
I really like OFF and try hard to make some progress, but this one is a spoiler. 
I did a fresh install, I even bought the UBI soft CFS 3 version just to be sure to have the right 3.1. 
I run Win 7 64 bit, Program in Admin mode. 
  
I did a web search on this, but found no obvious culprit. 
  
TIA for any help, 
  
Michael.
