Are you running justflight Traffic X ?

Right everyone, I have found the problem. I managed to pinpoint this issue to two pieces of scenery. Firstly, I downloaded some EGNF (Netherthorpe) Scenery awhile back. This was placed in my "addon-scenery" folder (it's the only entry in there at the moment). In FSX, when I enable/disable the "addon-scenery" entry in the Scenery Library, I toggle the glideslope problem on and off. Secondly, JustFlight's Traffic X seems to have some sort of play in this (cheers Jim!). Toggling "Traffic X Airport Facilities" on and off also toggles the glideslope/ILS capture issue. Therefore, it's EGNF and Traffic X that are the culprits. I have them disabled (for now) and everything is good. Cheers, VOZzer
