Okay, the merge-lines seems to be responsible for it! - However also very aggressive dp filter settings might cause the tooltip to show up slighltly away from the mouse (the tooltip will show up where the road would be in resolution 24) - however only when using --merge-lines the tooltip distance gets so great that sometimes it actually breaks using the routing tool in Mapsource. Aggressive dp filter alone (=10) cause no damage. > > > >> _______________________________________________ >> mkgmap-dev mailing list >> mkgmap-dev at lists.mkgmap.org.uk >> http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev >>
