Strange embedding of messages in RC3

[Kreator]

  I keep getting this strange embedding problem, everytime someone with firefox posts a message to the board
every subsequent post is embedded into that message all down the topic, I have reduced the message views in an effort to isolate even asked the poster to upgrade to latest Firefox version (was originally using Firefox 2.0)

The crazy thing is I tested it myself using FF3.6 and it does not do it for me all the subsequent posts are normal.

If anybody has any ideas for a fix could you please contact me

I will post a link to the problem http://www.animanon.com/Forum3/index.php/topic,588.9

it looks like part of your theme has an issue. i would first upgrade to RC5 and see if that fixes the issue otherwise I would upload a clean version of your theme and see how that works.

Thanks I`ve redone a test theme again and that appears to be the problem
