Hovering the words is not working. Is this only to me or all?
This happed to me before! When I clicked "Practice Skill" button (the timed practice one) the usual underlined words weren't appearing (I had to do it all by memory if I forgot a word or two) but it should appear back the next few minutes. Mine definitely did. It might be a glitch or something. Or maybe it was something so that they would know if you knew all of the words you learned before.
