I have relied heavily on the "Open message in conversation" function, because it gave me a tree of messages across all folders (Inbox, Sent, etc.) that was based on the person I was corresponding with. Now, the function is giving me a tree based on the Subject of the message. This behavior makes it useless to me. I've looked, and I can't find any configuration setting that would control this option. How can I once again get a message tree based on the correspondent's name, then sorted next by date? Thanks!
