PMDG B747X airport baggage vehicles

I am running Vista Business 32bits with FSX SP1 and Adventure updates and with Display set to full. When I park and open the cargo doors on the passenger version, the baggage vehicles do not drive up to the plane. They do with default planes. Anybody having this same problem? I have posted this question earlier, but have seen no reaction. By the way can anybody tell me where i can find my original post re this?I guess there is no need for me to write about my Autobrake problems with CH pedals and Logitech joystick judging from the heavy heap of correspondance about this.A Happy New Year to you all.Torben Jorgensen
