First I'd like to thank ckknight and chinkuwaila for fixing the problems with the wandering minimap-icons on foreign clients (will try it out today :)). Time to head up to the next unsolved things in cartographer :D :):
Everytime when I change zone the professions modules don't work until opening and closing the minimap. The icons (FlightMap, Cartographer Herbalism) aren't shown on the minimap too until I open the map and close it.
I'll check the newest build of cartographer today (since I didn't check it yesterday), perhapbs those bugs have been solve since yesterday :)
