On my Flash Gordon, the two targets on the side right side of the playfield below the in line drop targets have some weird behavior.
If you just tap them, they seem to work normally. If I press one of them down gently but hold it there, not very long but more than just an instantaneous tap, it makes the ball launching sound like you had hit the ball back into the shooter lane, and I believe awards current bonus. I get the same effect if I just hit the shooter lane switch.
At first I thought the shooter lane switch must be adjusted too close and the vibrations are triggering it, but that is not the case, and I have performed the same test making sure that the shooter lane leaf switch was not closing.
What could possibly cause this?
