Saving Mid-Turn without losing logfile?

New to Vassal, and so I am still working out some of the logistics.
I wonder if there is a way to save a game mid logfile and then take it up the next day when you fire up your computer? I am a very slow gamer and most of the games I play, I take several physical hours per turn and so I have to break it into 3 or 4 sessions. I used to just leave VASSAL open,which was fine, but now for some reason, VASSAL has been causing a shut down late in the night (I’ll figure that out later), so if I do a vsav at the end of a session, and reopen that vsav, all my notes and moves are gone. I can start another logfile, but then, if I don’t finish the turn, I have to vsav again, and again with no notes/moves recorded.

there are a lot of larger, multi map games out there so I imagine there is some remedy other than having to start and end logfiles multiple times during a turn and to have to send your opponent (I game PBEM) several logfiles.

Great forum by the way.
