I have recently reinstalled FSX on Vista x64.
All is going well, except there are no parked or static AI aircraft at any airport.
I have not installed ANY additional AI aircraft, such as WOAI, NOR have I installed any application such as My Traffic X.
To the best of my knowledge I have not altered any native install, and comparing the World/Scenery/Scenery folder with a backed up version, there seems to be nothing missing.
I have been running with the Traffic sliders at 50%, and boats and other bgls seem to be working.
But something must be, and I can't work it out.
I would like to avoid running a repair - as in my experience it would mean that I would have to reinstall all mesh add-ons.
I would be grateful for any assistance.
