I tested it on FF (latest) using my Mac and it works perfectly. I tested it yesterday using FF (latest) on Windows XP and it also worked perfectly.
I reported the Opera problems to the jQuery developers and I am still waiting for feedback.
RMS-Chef: Yes, that sounds good. I'll take a look at it. I'll also modify the query which loads the similar threads to make it faster.

To help me find out more about this problem please go to
