[Framers] Frame 15 UI annoyances

[Bertrand Meyer]

FrameMaker 2015, 13.00.333

1. I am saving in MIF 7.0. Any way to get rid of the pesky dialog that warns
me each time that I am losing information (I am not)?  It's driving me
crazy.
2. I unchecked "Auto backup on Save" in Preferences, but I still get my
folders polluted with silly x.auto.fm files. How can I get rid of them?

These issues did not arise with earlier versions. 

Thanks in advance,
