Double Voting

Has anyone else noticed their vote counting double? It seems like every time I vote the count increments by two. Also, I've seen the same in reverse. My short story I just posted went from 3 hits and 0 votes to 4 hits and 2 votes. Maybe one person hadn't finished reading yet and the other opened it up after and they both voted, but I've seen it many times in situations where that is extremely unlikely, if not impossible.
