Quoted from illiterate:

I have an issue with my machines where *sometimes* I will hit the magneto lock on the first ball and it will pause for a few seconds and then act as if I drained the ball losing my turn. It then ejects a 2nd ball for ball 2 and acts as if nothing happened and I can continue playing ball 2 all while keeping the first ball locked. This is an intermittent issue as it does not do this every time. Just looking for any ideas you guys may have..
