The "Post New Thread" page seems to freeze my browser, Mozilla 1.4 (Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624). All browser windows become completely unresponsive, and the application has to be killed ("This application does not respond" etc).

At the same time, the Java Console shows this error. Related?
