Good point. I had no issues with the prior and downloaded and updated before I remembered that I posted on hear last year that what they did didn't make sense. A shame they have made no attempt at another firmware. Maybe we are left with this one or the prior, if you can go back. So far the latest seems to work ok for me.
I can't believe how much the M9 has dropped in price. Well mine still works but it is getting near the point that if it crashes, it will be an expensive door stop and I would sell my fine lenses.
