OK, so this is interesting. I got the AI co-pilot to take off, then took back control. All seemed to be working.
Then I pressed tab, and the controls locked - nearly all of them. No input controllers (yoke, quadrant etc) worked. Keyboard didn’t seem to work (couldn’t move the camera). Mouse view didn’t work either. However I could move the controls I could see with the mouse, like the throttles.
Anyway, after a few seconds, it all came back. So I thought that’s a bit weird so pressed tab again. This time it also came back but took a bit longer. I couldn’t identify anything specific I was doing after pressing tab that brought it back. Repeated this a few times.
Paused and went to controls to check that TAB was really “empty”. Turns out it wasn’t - I had these bindings:
So I removed them. Went back to the sim, and this time it was properly locked - it never returned.
So restarted the flight (just used ESC then restart). Got off the ground again with the AI co-pilot (I only fly GA!). Took back control…nothing - hadn’t even pressed TAB (other than to check it was unbound in the controls menu). No controls worked. Couldn’t move the camera etc as before.
This time went back to the world map. and properly resarted the flight. Same thing - everything still locked. I can move the controls I can see with the mouse though. But that’s it. All this without pressing TAB now.
I’m thinking I’ve broken the sim at this point. So now a full restart of the sim.
Now on the ground, everything seems to be working. Phew.
So press TAB on the ground. Doesn’t change anything. As before, all fine.
AI co-pilot takes off and I take back control. All working.
I press TAB…and it locks up again. As before. This time, as soon as I touch the throttle and move it with the mouse, the other controls “unlock”.
So I press TAB again…and locked. Moving the throttle a touch unlocks it again.
This is repeatable. It locks until I move one of the mouse controllable controls - but not all. Turning the AP switches isn’t enough. It seems to be I can unlock it by moving the throttle or speedbrake. Flaps doesn’t do it.
It is very odd. Even pressing TAB in the ESC menu does it!
EDIT - and only in flight
