I started FSX and selected the 707 from my hanger. The nav lights were off in the selected plane. I captured the photos and that is that.
This was not a saved load, but just the free flight selection. see if that makes a difference.
Nope. No difference. I still don't see any nav lights.

Try your 727 and see if they work as well. We may have a loose electron running around.
Hmmm. Nope. No nav lights displaying there either. :(

I think I'll do a reinstall of both the 707 and 727 and see how it goes after that.

BTW, how are you feeling Mark?
Not too bad. Today is the first day since the operation (Tuesday morning AEST) that I have been able to stay out of bed for more than two hours. I was sleeping for about 4 to six hours for every two hours awake. Now I'm doing that after about four hours. So I still need to lay down and sleep/rest often. I'll bet the pain management medications are doing it.
