I use AES for jetways only and GSX for all else. However, I discovered something. In order to use Trakir5 I have to start FSX, allow the sim and Ezdok to stabilize, start Trakir5, then alt-enter back to full screen. When I do this FSX goes haywire. Scenery disappears, flickers, goes blank, etc. If I uninstall AES and only use GSX, same thing. If I uninstall GSX and only use AES, everything works fine. Once I reinstall GSX again, same problems. If anyone has a suggestion on how to overcome this issue I would appreciate it. If not, guess I'll just have to stick with AES. Thanks.
