Jeffrey,
Good news, the jetways appear to be working. I think I got confused as to the unzip and which folders to replace completely, as there are double jetways and on one occasion, the jetway disappeared after I activated GSX. I completely removed GSX, cleared registry, and reinstalled. The two now seem to be working together normally. I will have to go back and figure out what exactly I need to remove before (re)installing your zip.
In the meantime, just wanted to say that when it comes to the geometric limits and your efforts to fix them as much as possible – this appears to be a success. THANK YOU.
William
