Maybe being thick, but I am accidentally pressing the AIM-7 button on my Thrustmaster Hornet Joystick. When that happens I press the same AA buttons and the ones next to it on my HOTAS and although it cycles AA weapons I cannot get it back to NAV mode. However I can press the AA button the on the left of the cockpit and it goes back to NAV mode. Why can't I go back to NAV mode using the HOTAS?
