Airbus A320 A/P stuck

Hey guys ! While cruising and after changed some camera view, the A/P buttons stuck and none of them works… Sometimes does sometimes not. Why is that ?

Is it just the A/P or everything?

If using multi monitors, try clicking back on the main screen (outside of plane) before trying any switches/buttons.

Also, ALT-F4 (change windows from fullscreen to windowed or vise versa) sometimes regains control.

With me, and it only happened once, it was everything. I did all the screen change thing, nothing I tried would make the switches workable. Had to restart the sim.
