I am testing the demo version of GSX with interest to purchase. I am well acquainted with the aircraft editor. I have perfectly aligned .cfg file for the PMDG 777-200 and the 300. However, GSX does not adopt the alignment settings for the stairs and will not dock to the aircraft even while resetting Couatl as indicated on the manual. Additionally, when I enter the editor, the graphical representation is on point. However, in order to bring the stairs closer to the craft, I have to literally move the arrows to the center of the craft in order to force the stairs to properly dock and align to the door as I want it. Is it because this is the demo version, or due to some other reason? Any suggestions?
