I always play FSX in windowed mode actually, frequently tabbing on long hauls to other windows. Never had the issue, but to be honest I rarely ever use the escape button in FSX and haven't been playing SH3 at the same time.
So its possible but I haven't had a chance to correlate those two games and this bug.
This is a very obnoxious bug because it makes you paranoid. Gotta save often incase you lose all your progress! I think the first time I get this bug after getting a Knight's Cross worthy attack in that has to be rolled back I might not play SH3 for a month.
Out of curiosity, is possible to bind the Escape key's command to another button or a clickable spot in the GUI like with everything else? Putting the escape menu on some rivet I can click somewhere in say the Obs Scope or something would make this problem a non issue.
