I just bought JP and it needed some long due attention. What I can't figure out is why the ball popper/top eject is firing anywhere between 1 - 5 times but usaully 4-5 times while the game is being played and there is no ball to be popped up. After the 5th pop the launcher will sometimes give one shot too .The switch seems to work properly and I cannot find any wiring issues. It never pops more than 5 times. The CPU has the 4.04 version, is that an issue?
