The software keeps losing settings. I THINK this is only in the latest version of the beta - I am currently running 0.80.3597
I am on Mac, I have the button below the scroll wheel configured to trigger Mission Control.
I lose that setting, and the button does nothing.

I also lose the wheel setting - I have it on smart shift, but it turns this off, and I am locked into free spin mode.

I thought maybe the assignment of the button to "Mission Control" had reverted to the default, which is to switch wheel mode (because of the smooth scrolling symptom), but pushing the button does nothing to the wheel when the software has forgotten settings.
