is there any particular reason that you hijack a thread and destroy threaded views? if you want to open up a new thread, copy the mail adress and write a new mail. therefore a new message-id is created. Thanks in advance. :)
Oops, sorry.
I didn't realise that emails had a message id. If they do, then another important question is why doesn't Apple's Mail use them. It threads emails by subject which breaks an awful lot of times. I have thought to myself a few times... if only emails had thread ids...
...you learn a new thing every day. :-)
