What I think happened was that when I sent in my original complaint, they saw PDF problems?, Battery issues?, Send reply no XX.
When I sent the second report, with the Picture, they probably got hit by a clue by four.

I wonder whether this will light a fire under the development team, now that their easy solution of rolling back to the old firmware is gone.
So have to see how they respond to my request for the firmware it shipped with.
At least some thing's worked under it.
