The jetways don't move when I select it through GSX. The wheels at the base turn as if lining up but thats it. The beacon is on but it doesn't move.
Doesn't happen here, and nobody else reported it. SODE jetways either don't move at all, or they work. I assume you have updated GSX using the latest FULL installer, have you ?
GSX seems to be stuck in the boarding mode each time.
What do you mean with "stuck" ? You either see the jetway selection menu, or you don't, but boarding will continue in either way.
Is there a way to get them to move other than with the GSX menu?
GSX ask SODE if a jetway ( considering your plane, the doors and your parking position ) can work. If SODE replies the jetway is ok, you'll see the selection menu in GSX, otherwise it won't make any difference: that jetway, on that plane, on that door, at that position, couldn't work even if you could call it from the SODE menu instead. Of course, GSX will give you a clear warning about this.
CTRL J works at DFW but not at IAH or MEM.
That's exactly how it's supposed to be. Only KIAH and KMEM have SODE jetways, and SODE jetways work using the jetway selection menu during Boarding/Deboarding in GSX.
Scenery using the default FSX system will continue to work using CTRL+J
The GSX parking menu will tell you which parking have SODE jetways, appending a "/JS" to their name. If you see only a "/J" it means it's a default CTRL+J jetway. And if there's nothing ,it means there's no jetway there.
