I'm glad the problem has cleared! Although I'm not quite sure how it
cleared, because the World.vis file you had backed-up didn't change. And
none of your files changed except for the facility.bgl file. That file, I
believe, is a remnant from FS ver 5, and contains airport data, most of
which are in those AFD BGL files we've discussed before. It wasn't on my
Hard Disk either. So I would say it is optional. There are a few airports
in it that are no where else, so if you want, leave it in the main Scenery
folder. Any duplication airports shouldn't appear.
Perhaps another bgl file was missing before that caused the problem, and is
now there. Hard to say.
Your World.vis file is fine. I don't see a problem with it.
Good Luck and Good Simming
