Now, after I fixed the seated pax thing, at least for the 300ER (which is kind of a GSX/installer problem), I now face the annoying door problem. Doors open and close the whole time during boarding or deboarding, neither me nore GSX have full control over the doors. Even if I disable all automatic door management in the GSX 777 profile, still PMDG (I guess it's PMDG code) is fiddling with the doors in the background. 1L opens all the time (even when there's no stairs or jetway). I can't close the cargo doors (they open again all the time, until I undock from the gate). The back stairs only leave when I close the door. But after closing it, they open again. So I have to do it twice.
I'm pretty sure there's nothing that can be done on the FSDT side. Since this is PMDG, not enabling the pilot only to have full controll over all doors. Oh man, they did some good things, a few decades ago. But now....
