.cfg file opener editor ? skymap

[flowtron]

I highly suspect the original poster has got "hide extensions for known file-types" turned on - this would be indicated by a text-file icon and no visible extension after saving a simple file written up via Notepad. I suggest turning on this feature, or - if you've copied the default_map_settings.cfg (do you see the .cfg for it?) just don't add (a 2nd!) .cfg to it - cause the file would then be called my_map.cfg.cfg .. and unless you saved your map as my_map.cfg.cgz it doesn't match the maps' real filename ;-)
