Mr. Dowson,
Just purchased Airbus X which comes with RAAS Professional which, as I'm sure you are aware, uses your Make Runways application. I also use ORBX scenery - I have most of all three areas, North America, Europe and Australia & New Zealand (considered 1 "area" - Oceania). The thing about ORBX is that you can only have one area loaded at a time. They have a small application called FTX Central that easily allows one to switch areas or revert to the default FSX scenery. Based on my peeking under the hood and the messages shown during FSX start up, it appears this application re-edits the scenery.cfg file every time you switch an area.
My question:
Based on what I read above (I really appreciate how you were able to break things out) I think I would have to run Make Runways after each time I switch ORBX scenery areas. In other words, it Make Runways needs to see and read the newly edited scenery file. Is that about how you see it?
