I am trying to edit my home airport (KLNS) but whenever i either A, create a new runway/taxiway, or B, create new hash-marks it causes problems. First i edit it and it looks fine with no faults. Then when i start flight simulator and go to that airport its fine for about 2 minutes or until i move. But once i move or its been 2 minutes it causes the screen to go black and freeze, eventually crashing Flight Simulator. It only crashes when i actually am atop the runway or taxiway i just created, if i am on a original runway i am fine. If you could respond or email me at Mbender@midsar.org that would be AWESOME!
Note: i am using AFCAD 2.2.1.0 And FS9 .
