Regarding nr two, it's very simple. We hear a GSX voice prompt asking if we would also like to deboard the crew. However, we don't understand how/where to respond to that question. Since there's no prompt anywhere to answer yes or no.
Well, of course there will be a prompt, unless you closed the GSX menu using the GSX Toolbar icon, which is something you shouldn't do, for as long the service lasts.
With a recent update, the GSX toolbar icon will never be closed automatically by GSX as it used to be, because now there's an hotkey that will open/close the menu
keeping the Toolbar icon still ACTIVE and even the X button will not close the Toolbar icon as it did before, but it will just hide the menu.
The updated manual, of course, clearly explains this and how has changed from the first release, and also explains why you should never close the Toolbar icon: doing so will result you MISSING any message from GSX and ( like in this case ) any pop-up menu GSX will need to show in between services.
