The "Filter E-mail" drop down is now greyed-out and won't function. I often use it to clean up emails by going to "unread," but that wasn't working after the last (forced) update. I figured out how to disable it, but now can't figure out how to bring it back on board (and lost the directions I used). One response to a similar question said go to "tools," but that's not an option on my screen.
