When reviewing questions in the queue, most specifically close votes, what happens if a mistake is made?
I was reviewing a particular question that I fully intended to vote to close (it was clearly a third-party plugin question), but I inadvertently hit the "Leave Open" button.
It doesn't appear that I can go back and change my vote - either that, or I just can't find a way to do so.
Is there a way to change my vote, or is it "hard-and-fast" once set?
