Been fighting this one all week. it's obvious that couatl is working as it brings up the airport scenery. however when I try to activate GSX I get an error creating child window message. you ever sen this before?
I haven't seen it but, of course, it's nothing that has anything to do with GSX, the child window which is being referred to, it's not something specific to GSX, it's the standard green text used by many 3rd party applications to print messages, with some using it through FSUIPC, but GSX using it from the standard Simconnect interface.
There was a post on this site, indicating it could be a problem with the Windows 10 insider program:
