One of the features I very much appreciated with my iMac (late 2013) was that when scrolling through messages displayed in the In Box of my Mac mail app, each one that I scrolled past would automatically have its status changed from Unread to Read. Since upgrading to EC, this no longer works. In order to have the status change, I either have to open the email or right-click and manually change the status. Anyone else notice this? Fixes?
