I've been lazy at reviewing recently :-( but I decided to do some today. I was in the 'first posts' queue and decided that the question was perfectly acceptable but not worthy of upvote, downvote, comment etc. So I went to press the 'no action needed' button only to find that it was greyed out. I could not find any way to activate the button.
Is it broken? Am I using it wrongly? I can't remember for certain if I've selected this option since they changed the way the review queues work but I was fairly sure I had.
