Hmm...what does the console say? We just tested this on 9014 and, when clicking on an unread item, it's marked read and the unread count DOES decrease on the folder. And is this on the Inbox or is it in another folder? 

Sorry, Not sure what you mean by console.

Any folder, including inbox.

No problem, Curtis. There should be a way to enable Developer Tools for your browser. This will allow you to right click on a blank space in the webmail interface and select "Inspect" from the context menu. This will open a new tab, or a new window, and give you a look "behind the curtain" of the page. You'll want to select the Console tab, and refresh the page, then click on a message. If there are issues, you'll see some red errors on the Console screen of that second tab/window.
