Hello all. I downloaded, installled and activated the 737NGX in my FSX. when I load the aircraft and begin the simulation, I cannot access the options and fuel menu, and the keyboard commands, save and load state and edit failures are empty. And when I finish the flight, I should go back to the initial menu of FSX. It happens, but it gets stuck, I can´t do anything anymore, and have to finish FSX in the task manager. Did anyone experience the same problem or have an idea how I could solve it? Best regards, Rafael.
