I accidentally undid my upvote on a question thinking I was upvoting it, but it undid my upvote, so I click again to re-upvote it, but it is locked unless the question is edited.
I can post a comment asked the submitter to edit their question so that I can re-upvote it, but that seems rather round-about.
Is there a better way to do this?
If not, shouldn't an 'up undo up' pattern be allowed if in a short period of time? You can undo your up vote if it is a mistake, why not undo your undo if it was a mistake?
