I have been encountering a problem with Flightgear 2.1 where anything under the drop-down menu specific to the aircraft that I am using is not working.
For example, when I try to use the Boeing 777 that can be downloaded in the Flightgear client, anything under the 777 tab of the drop-down menu such as the Handy Viewer, Livery Select, and Autostart do not work.
I have uninstalled and reinstalled flightgear over and over but I still can't seem to fix the issue.
