Hi Michael, I've attached an update for you to try - to apply this update right-click on the app and then go into drive_c/moi/ - maybe rename the old moi_touch.dylib to something like moi_touch_old.dylib so you can revert it if you need to, and then copy this new version into there.

Then hopefully this new version will allow your mouse wheel single-finger scrolling to work as before.

And that's intereseting that the single-finger double tap works for "smart zoom" on the magic mouse - on a trackpad that's a 2 finger double tap and it should do the same thing as the "Reset" button at the bottom of a viewport now.

- Michael
