Moom 3.2.6 has been released with a few bug fixes for snap-related actions. Users had reported some issues with snapping when working with zoomed displays and when customizing toolbars, and some reported decreased responsiveness in certain apps. We have addressed all of these issues in Moom 3.2.6; you can see slightly greater detail on these changes in the official release notes, if you wish.
App Store users should see the update shortly, if not already, in the App Store app. Direct users can update via the in-app updater, or by downloading a new copy of the app from the Moom page.
