Double posts???

Recently, when I post a response to a message in a thread, I find that the message has been posted, but I also get a display with the regular post in it and a warning message that says I can only post every 30 seconds and I have to wait to post again, but the post it is trying to "post again" is a post that is already posted - make sense. This started a couple of days ago and continues with the quick post feature. It is almost like I tried to post the same thing twice, but I really didn't, although the forum seems to think that I am trying to do this.

Can any of the mods help with this problem?

Thanks.
