Had this happen in the Off-Topic section in the Three-Word Stories thread just now. Say there's a rapid-fire exchange of posts, between two people, say I'm A and the other is B. When B types a post, and I type back, B's post will appear in duplicate (when it didn't before). To help..... - No quoting of messages, just a simple reply (it was me and me and lipton doing the exchange a few minutes ago if you want to see the actual exchange. - The double posts does go away after creating another post. - I'm on Win 7, Firefox 3.6.13 and wearing my French Maid outfit.
