I know that if your answer is edited, that you are then allowed to change your vote.
However, if you are the person who edits the answer, should you be allowed to change your vote?
The reason why I ask this is that one of my answers recently had a one character whitespace change, and immediately afterwards, was voted down... now, this might be co-incidence ;-) but it is a big one if so, and what I believe happened is that the question was edited, explicitly so that the user could change their vote.
What are your thoughts? Should this be allowed?
Edit: OK... I get the hint, this is as designed. I would delete the question, but too many people have disagreed with me, so now I can't ;-).
