Wish I would've seen this a few minutes ago...lol
I sent most of the stuff to oblivion and am starting from scatch..
well didn't delete the models, but the Ah terrain editor, and then did a fresh install..
All this came about from trying to use the settings from "lafld0g" with a differnt texture, in combination with stock runway and tower, to try to find out where the trouble was.
When I went to build the file...i got this error:
"Out of Range X -2641.8 in RWY0"
I'm starting over one step at a time..Just going to try to add a different texture to the ground underneath a simple airfeild with a runway and a tower.
Just had to clear my workspace

I'll wing an email at the first sign of it doing the same thing...
dale@hitechcreations is correct?
