When going in and out of the Constraint Manager, I've had my top drawer front drop down over the middle drawer front, several times. Ive tried to duplicate the exact series of steps that causes it, but so far have been unable to. I've attached the cabinet that it has happened on.
Do you by any chance have this cabinet before the error happens? I will keep trying to make this happen myself for now, but if you have a seed that helps, that would be great.
