It now happened a couple of times to me, and I'd like to let you know. If I delete one of my replies, and then hit the "reload" button (I usually do this, because I often see a chached page with my reply still in, and I want to make sure it's really gone before I re-type it), I get an error page. Sometimes it says that the whole threat was deleted (which is of course not true), and sometimes it reports a "access violation" by me which "got logged". I'm frightened to death everytime I read this... :-)
