There is in my opinion a problem that overview maps sometimes get created smaller than the actual map (i.e. when using gmaptool to create the mp overview map). I don't use mkgmap for overview map creation because it long was pretty buggy. Then in Mapsource maps will be cut off, while the data actually continues. Try a huge overview map (i.e. whole of europe) with your maps, to see if it is not an overview map problem instead of a real map data failure. -------------- next part -------------- An HTML attachment was scrubbed...
