You'd think Yamaha would urgently want to find out as many bugs as possible so that they have time to put them into their next OS. It really looks like they are putting their heads in the sand. Maybe for every one informed call about a valid bug there are ten people who call whose "bug" is solved by reading the manual more carefully. I have had pretty good luck in getting in touch with Yamaha over the phone, even though it can take several days to reach a human being. It's better than some other music related companies.
