I think there's a problem in the part of the code that parses Lat/Long text entered in the "Area" tab of the Map Manager. If I change the degree display format in the "Misc2" settings to S dd° mm' ss.s", it seems the pre-populated values in the "Area" tab are incorrectly re-parsed by the software to determine which maps to download. This generates errors when trying to retrieve Google maps in bulk, and although VE reposititories don't report download errors, the tiles retrieved are blank. This does not affect auto-downloading of maps as you browse, only downloads requested via the Map Manager.

I experienced this problem with Maemo Mapper v1.4.7-2
