Everything was working fine before I read the post about the "offline" installer. I thought that running it would only verify that I had everything installed correctly, but my doing so apparently introduced a glitch that I cannot undo. When I spawn my aircraft at a gate, the GSX icon appears in my toolbar, but clicking on it only caused the menu to flash and then disappear. I have tried several times to run this "offline" installer again but I still have the same problem.
