Almost every time I start a new thread in the forum (and less often when I add a reply to an existing topic) the browser enters an infinite redirection and I'm no longer able to enter the site again until I remove all the cookies with "activestate" in the domain name. I thought it was a Firefox-only issue but it's just happened with Opera. I reported it the first time it happened but never got an answer. It's not as serious as then (now, the workaround of removing cookies works) but I find it surprising.
Am I the only one who suffers this? What am I doing different than you?
