Hi I looked at (display . all) but it is not doing what I am looking for, namely that I see all messages in threads which contain an unread or ticked message. I couldn't find this option under the (display . ) group parameteres, so I am wiondering: is it possible to have such a behaviour? It would make much easier when trying to follow an older thread which was picked up again. Cheers, Rainer -- Rainer M. Krug, PhD (Conservation Ecology, SUN), MSc (Conservation Biology, UCT), Dipl.
