I do experience the same thing. It used to work fine until the recent updates. Everything I do will take 20seconds or more before Evernote would respond. Also, when I copy an entry with a tick box, it automatically tick that off even when I only highlighted that entry so I could move it on another list. Made me think twice if I would renew my premium account. This really is a big consideration because as the thread starter said, it kills productivity big time.
