I'm having a problem understanding how the overlap of symbology works. I have two separate point shapefiles that denote different types of airports. One airport file (the base) is a light blue circle. On top of that I overlay another airport shapefile (the airports of interest) and that is a pink star. Now when i turn on both layers I would expect those airports that are coincident to have a pink star on top of a blue circle. This is not the case, all I see is a blue dot. My legend shows that definitely the pink star layer is on top of the blue circle layer.
I just tried in the ESRI product and that shows the two symbology even if they are on top of each other. Am I missing something to make that work in MapWindow?

Are you looking for the collision mode:
sf.CollisionMode = tkCollisionMode.AllowCollisions;

I didnt know that existsed. :) I'll experiment with it. Couple comments:
1. Shouldnt this be off by default? I think the user actively avoiding shape collision should be a conscious effort rather than the other way around.
2. The documentation says "Sets collision mode for labels of the shapefile.". Im hoping that's a typo as label collision is something else. This is for shape collision.
Thanks for the great work!!!
