Hello! I have owned the Captainsim 767 Captain II for P3Dv4 for over a year now. Since then, there have been 2 occasions prior to long flights where after starting the engines, the #1 throttle lever will not advance. When I move the little throttle on my joystick (which is set to move both thrust levers), the #2 lever advances normally, while the #1 lever stays idle and can only be moved manually by dragging it with the mouse.
I have tried switching the autothrottle off and on again, re plugging in my joystick, and changing my keybinds and it still doesn't work.
How can i fix this issue?
