Looks like DXAtlas makes DXBase 2007 v 1.10 die every time i connect this map software from DXinfo window. Map version is set to v2.1 or higher in user options (General). Running W10 64 bits. I think this is a new problem, but I can't figure out how it happened. Viewing DXAtlas outside DXBase is no problem, even if DXBase is running. 73 de Knut LA9RY
