when I had my JD, I had the same problem, except it would jump out and into the outlane. That really sucked. I did some searching online and found a couple old forum posts saying that bending the end of the wireform will solve the problem. What seems to be happening is the end stop is causing the ball to bounce up and out, so you want to bend it up so that when the ball hits the end stop it doesn't bounce. I did it to mine and it worked great. It didn't take much of a bend, so I think what happens is that over time the ball constantly hitting the end of the ramp causes it to open up and bending it back fixes the problem. You may find that when you bend it you also twist it a bit, so it may take a bit of tweaking to get it right. But that's what Judge Dredd is all about right? Constant tweaking to keep it working just right!
