Hi
Pls use last TopoLusitania available (v0.94). Mapsource 6.16.03 patched displays TopoLusitania w/out problems.
See TopoLusitania Blog for a new available Typ. The use of a Typ not prepared for a particular map can origin that the map is not displayed properly. If you want a more complete reason, write to TopoLusitania team. Mail can be found in TopoLusitania blog's title
