I am seeing this behavior as well. First it seemed to be limited to jetways getting all messed up when I tried to customize some parking spots at KJFK and KCLT. After one iteration of the edit dialog, GSX becomes completely unresponsive to all menu items or key shortcuts. Now today, I haven't tried anything other than connecting a jetway and GSX has become completely unresponsive, and SODE says I don't have any trigger able objects (despite a jetway clearly being connected).
By unresponsive menus, I mean all items in the Add-Ons -> Couatl settings, Couatl Live Update, and GSX menus. I can't even reboot it, which is incredibly frustrating for something that has generally worked consistently well for years.
(And, for what its worth, the voiceover is incredibly annoying, to speak nothing of realism.)
