EV Scroll wheel bug fix#139

If the EV setting is set to the darkest using the scroll wheel (-8) it gets stuck at the bottom and can’t be scrolled in the reverse direction. To bypass this the user must use the app or hold down the scroll wheel to reset it to auto.

Admittedly this is a fringe use case, but it would be nice to have fixed nonetheless. Thanks for reading these as always!

Noted, thanks. We will fix it.
