As I, apparently, don't have the same issue with GSX as others here is my problem...
If I install GSX (latest version) and then start FSX all is well, GSX works.
If I then close FSX, alter the scenery library with Scenery Config Editor, which I do regularly to help control VAS usage, I get the GSX menu but clicking any of the options fails to bring up GSX windows. There is also no cache rebuild which I used to have after changing my scenery options. FSDT sceneries work without a problem now since the couatl update (KORD, KLAX, KJFK).
The only way to get GSX to work again is to reinstall it.
So... do I need to manually clear the cache to force a rebuild (if so what files need deleting?) or is this an issue that requires an update of GSX.
The couatl log just shows a disconnect from FSX ...
couatl v3.0 (build 3154)
panic log started on Sat Aug 08 13:55:37 2015

Thanks for your help
