Hi,
on my maps I use 4 layers of DEM. The problem with shading appears mostly, when using medium or low detail level in Mapsource, probably when Mapsource use layers with lower resolution. Pressing Ctrl-G shows overview map and I think it always display correct shading.
Other peculiarity is that problem appears only at sea shores, I don't find it when viewing land area.
