I recently purchased and installed the flipper board replacement for my judge dredd which I have on route. A couple problems: 1 I had to move the start button sideways to get it to fit, and it is still a tight fit. Secondly and most important, if I have the magnet attached vertically, it sticks to the plunger on the kickback, and one of the flippers won't flip. If I lift the playfield up it works fine. I had it oriented sideways initially, and did tape it down, but I came back a week later and the magnet had moved to a point where it wouldn't flip at all. Am I missing something?

Any ideas?

Flipping the magnet did not solve this problem.

Yes, it is the one specific to JD. I ordered it from Marco.

Can you describe how you taped the magnet. I did this also, with gorilla tape. I put pieces all around the magnet, as well as a big piece over the top of it, but it still ended up moving. I like the flexibility this board offers but dealing with this magnet has been frustrating.
