FSX can do strange things. For instance, today, my FSX has decided that it would not show landing and taxi lights on the ground. The setting was still set to show them, but it has just decided not to. So I turned it off, went back to FSX, and it then shows them on the ground. :o
So I turned the setting back on again, and they were showing like they should. For a minute there, I was worried the setting was going to be reversed somehow.

FSX sure can be a strange beast at times. :-/
