I have installed the Sparky 747 and set it up for a flight. When taking off, I move the thrust levers forward, but the plane does not move. The engines just roar. The parking brake is off; there are no conflicts between the sim and the joystick, then when this happens, I cannot bring the thruster levers back down with either the mouse, keyboard, or the joystick. So, it seems something is hanging, but not the simulator, as I can move to the menus, etc.
Any ideas, please?
