I've periodically been experiencing unresponsive flippers. Thought at first it was my fault, perhaps not making adequate screen contact, etc. But no. This is a fundamental issue across all eight tables I own so far (although I have been playing Big Shot a lot lately and have therefore seen it there most). As a test, I let the ball sit unplunged while tapping a flipper at approximately 1/2 second intervals. Every time, I was able to see a flipper fail to react, sometimes three and four times in a row. During, play it is absolutely intolerable, pushing me to the brink of abandoning TPA altogether. Does anyone else see this?
