A bug discovered in the horn, I thought that was the button of my G25, but looking at the options realized that indeed is a BUG same.
I do not know exactly what the cause of the problem, but it only occurs when the car this off, squeeze the button for the horn (both forms if the keyboard or the G25), and no sound comes from, if the car is on the bug disappears completely, recorded a video showing.
I also tested the FXO with another kind of horn on another track and the same thing happened, I tested in the X10 and this did not occur.
A bug without virtually nothing of importance, but is a bug anyway.
