Fred, It definitely crashes. I don't even get a Save dialog - the app dissappears from the screen and from the apps thing at the bottom left of the screen. It also just crashed when I was trying to look at the Settings. The only thing unusual at the time was that it was struggling to establish a GPS fix (the GPS is on my windowsill with a poor view of the sky). Maybe the problem is bigger. The behaviour I observe is very like that described in a post in another forum, although no answer was forthcoming: Does MM have a log file? Any pointers to good documentation/help for Maemo Mapper?
