I'm not sure if anyone else has encountered this problem: Sometimes during the map download if the internet connection gets interrupted and causes the map file not to load completely. Part of it is still saved in the MaemoMapper file storage directory, thus Mapper thinks it has the map. However, Mapper does not show that particular map file. (I guess that's because it is corrupt and it detects it during loading the map.)

What I end up doing was hooked up 770 to PC and using file manager (maps are saved in MMC card) browsed through all the map files... and deleted the ones that were corrupt/incomplete. After that Mapper did redownload the maps that were missing.

Gnuite: Can you add couple lines of code that checks the file, if it is corrupt or incomplete (or if that is not possible then somehow detect situation in Mapper when it did not load and show a specific map file properly?), and then redownload the map?

There is somewhat similar request over here:

That might be a good addition as well to force (re)download maps by area, similar to the function already in Mapper download maps by area...
