Thanks a bunch, Ray.
There was me thinking that the SODE option would have all jetways linked to the GSX drop-down menu 'Operate jetway', but as I have discovered, does not appear to be so.
Last night, at Orbx's ESSA(Stockholm Arlanda), the jetway is clearly there to be seen, yet no matter what I tried, be it GSX's 'Operate jetway' or the default Ctrl+J, the jetway would not budge.
PS. Forgot to ask, Ray, does that link fix GSX version 1, or does it only fix GSX2?
