On my ST premium while playing it seems that when I hit the drop target hard and dead on, some times it doesn't indicate a hit. But, when I tested it with the glass off it worked every time. Does anyone know if this is normal? Maybe it is registering, but the software doesn't play the "hit" sound so I'm assuming it's missing, but I'm not really sure.

Is anyone else seeing this?

Hmm... Mine is new and it's doing it.

That describes it perfectly. I've looked at it but don't see how it possibly isn't working. The mechanism seems so simple to not work.

Thank you! That seemed to fix the problem. Works perfectly now.

I didn't get the blue spring with mine. When did you purchase your game? Maybe this is something new they are doing.
