Well problem solved, how? absolutely no idea. I relocated to a reliable airport Sydney then proceeded to conduct about 6 full ILS approaches with 6 different aircraft models, some CS some not. They all worked fine including the CS 707 and 727. I started with the 737 (same problem) switched to a DC-3, then a Baron, then to a Twin Otter, to the 707, the 727 all worked normally and as expected, finally back to the 737 and lo and behold now it worked as it should. Go Figure I have no idea. The only thing I can think of that resetting all the aids autopilot etc on another model some how reset for the 737 at the end.

Still reckon there is some thing dodgy with the panel switches on the 737 that I have installed sometimes they work sometimes they don't for some reason. Ah well. Then again maybe it is just FSX.

Happy again.  :)
