Thanks! Oh, while I was looking at my scenery library, I noticed that Default Scenery and Default Terrain had the lowest priorities, would it help to move them up?

Add-on scenery goes to the top because when FSX is loading scenery, it starts at 1 and goes down the list. Once the add-on scenery is loaded, it ignores the default (because the add-on scenery was given precedence). It would look silly if an add-on airport AND a default airport were both seen together. ;D
