It's been put in the thread according to the time sequence because the header you mention is missing. So, it just *appears* to be threaded, but the node where it gets put as a reply is random (here it is put as a reply to me, that is why I noticed there is something wrong). That header is missing from all of David's postings, now that I look, and he's been using several older versions of Thunderbird which can't all be broken. So, I assume he's using a broken mail gateway which strips these headers. Kai -- Kai Schätzl, Berlin, Germany Get your web at Conactive Internet Services: http://www.conactive.com
