i am trying to tell gsx that but it messes up when i try to ( see attachments for more info )
The problem doesn't have anything to do with GSX, it's an FSX bug that happens when trying to display a standard Windows dialog over the graphic screen. It doesn't happen in P3D.
It should be fixed if you move the GSX parking customization window outside the area covered by the FSX screen, so they don't overlap anymore. If your monitor doesn't have enough space, you might have to resize the FSX window, at least during editing the airport, so the FSX window and the GSX window will not overlap.
