Drawing (by 2 users)

This happened to me twice, and both times were after I had downloaded a long route. Both times, the only available fix was to do a "hard reboot" by selecting page-OK-power and then selecting "yes". That restored operation, but it also deleted the downloaded maps, routes, and waypoints, and forgot my preselected options.

(In MapSource, I had used the "Select maps around route" option, and both times the total memory associated with the selected maps was much less than 115MB - one was 59MB and the other was 63MB. And in three years this has never happened when fewer maps were loaded. My experiences therefore suggest that the actual working memory available for downloading is much less than 115MB - I don't yet know what the actual limit is.)
