So there's a bug in that if you have joystick axes assigned to a joystick not presently plugged in, when you "Start" controls (mainly for shared cockpit mode), those axes cannot be manipulated.
It has been fixed.
OK, new builds have been posted; just redownload at the same links.
So Pablo, I noticed that you were connected to the wrong server. That means you were using an older build of the NetFlight app. The latest was built today at 13:31 MST.
