Undoing an old vote cannot be recast because vote is too old
I got an answer to a question that had me very very stuck. (This is it: WPF - Change a style in code behind)
I upvoted because I was happy that I got an answer. But then I said to myself, "you should just check to see if this answer even works before you upvote." So I undid the upvote and went and checked the answer.
Turns out the answer was fabulous, I wish I could up vote it several times. I was surprised when I tried to re-cast my upvote and was told that my vote was too old to be changed!
I had not even voted! I had un-voted? Does this message mean that my un-vote is too old be changed? If so that is sad. I got a great answer that deserves to be rewarded.
