I can repeat and confirm the error reported here IS fixed with the latest update.
Umberto, when you mean it's fixed with the latest update, you mean in some unreleased update, right? I still have version 2.9.1 as the latest. Do I click Check and get it fixed?
1. Started with PMDG 737-600 at LSZH
2. From From the GSX menu, I selected Start Boarding.
3. After aircraft configured and passengers loaded, I selected Prepare for Departure from GSX menu.
4. After pushback completed I got never ending loading screen. Confirm good engine start is not possible. No matter how often i tried or reload the sim
I update GSX Pro whenever i start the Sim. It is always 100% up to date!
BUT
I already have to restart the couatl thing since GSX itself will not load properly.
And I still have the problem that confirming a good engine start wont work properly. I have to stop couatl process via Tskmgr and then i can move my plane again.
