It wasn't like that when I first bought it, but when I'm playing a game, the button often doesn't come back from being pressed. This is a physical problem, so you have to go through the trouble of triggering the button you press. I try to find a position where the button can move smoothly by loosening and closing the screw on the main shaft of the button, but it doesn't get better. Is there any countermeasure or workaround? I'm in a lot of trouble.
