GSX LvL 2 Custom Jetways

[qcaptain]

Hello Just a question Ive set up 2 new jetways at YPAD and when the attach to the 777 with 2 jetways after de boarding has started the jetways slip or move toward the nose of the plane. What have I not set up right?---maybe the plane moves although Ive  got park brake on....
Cheers Greg.

That looks like as if the airplane was moving indeed. I assure you is not GSX doing this, the only time GSX moves the airplane, is during pushback.
