I'm waiting to see what Magnus Danielson has to say, as it was he after all who suggested adding caps in parallel to the pull-downs, and also series resistors.
Thinking about it retrospect, I think he may have meant the series resistors to go between the pull-downs and the chip, rather than where the schematic fragment showed them. I don't *think* switch bounce is an issue here, as it will all settle to the right answer pretty sharply. Magnus, are you there?
