Well that is exactly what I was referring to. The problem is that if I 
place POI at the very left, they are not visible in Mapsource (when 
zooming in). Maybe the overview map should be rounded to be bigger than 
the tile below?

Some time ago (about 6 month) in the east of Austria Geofabrik cuts, it 
happened that some part of the map got dropped. Since quite a few time I 
could not find such problems anymore with real osm data, only with my 
"testmap".
The thing is, that gmaptool to create mp, and maptk to compile it, get 
the rounding right (or so much better that no more error is visible).
