The home machine and technicians had nothing to do with Kane finding the glitch. If it did, he'd have never told Nestor about it and the technicians would be all over this play.

I wouldn't be surprised if an IGT programmer programmed the malicious code in intentionally. I've worked with many software engineers in my earlier career, and they all have this ego that makes them program their own little stamp of varying sorts into every code they write.

I was sent a question regarding having to constantly push NO every time you get a winner that you will not double-up on. Yes it's bothersome, but that's a very small price to pay. And you can't hit "Don't Ask This Again" because you do not want your hand to tally up your winning credits on any hand you want to up the denomination on without giving you the opportunity to go for it. That's when a hand is REALLY over.
