Did some googling and found this: http://www.vbulletin.com/forum/forum...rking-on-reply

It seems there won't be any fix for this issue from their end unless they stumble upon some quick solution. There may possibly be a fix in Chrome at some point if it is indeed a browser bug. Until then, probably not much we can do aside from use workarounds and wait, or switch to another forum software (which I don't think is in the cards right now).

In other news, seems vBulletin's support team is keeping up their tradition of acting like petulant children - though some of the other posters there are too, to be fair. Still, it baffles me that any company handles customer service like that.
