Hi Umberto,
For now I can confirm:
* Issue with GSX catering, refueling and boarding is now fixed, popup menu options now work correctly.
* Sode jetways that came with the scenario work as programmed by the scenario.
Concerning the customisation of the jetways:
* Can confirm that the file identified on the top of the window is now correct and the gates in the list now come from the right AFCAD (see attached, screen).
* I'll try to customise jetways after today's IVAO event, don't want to mess with it now. I believe it will work now.
Thank you for all your help.
