All of a sudden, I am unable to save missions. This iis espeically unwelcome when I suspect I'm going to blow an approach and want to save just before I do it.I go through the procedure and assign a name to the mission to be saved and the program appears to accept it. but when I do blow it and have to stop there, the "saved" mission doesn't appear when I want to load it.All the adventures I've purchsed are available. Anyone got a clue?.

That very same thing has happened to me. I can't track exactly when, only that it must have been in the last few weeks or so. In my case what happens is that when I press the key to save a mission under way, I get the "Save Flight" box instead of "Save Mission". Most frustrating!

Solved!

I must have been blind for some time now - it turns out that the dialogue box says "Save Flight" even when you are in a mission.
