Just flew the KC-777 in MSFS2024.  It worked great until the sim bug where the mouse stops responding.  Esc out to the menu, Esc back into the flight, the mouse is now responding, but the throttle moves without adjusting thrust.  I toggle Autothrottle ON, then OFF (I'm hand flying), and the throttle responds again.  Otherwise normal flight in the KC-777.  I'll check the KC-46 next.
