The new (and screwy) system will not always sort the latest PM at the top (or bottom) of the collection of threaded mails. What I've noticed is that it sorts the Messages latest at the top down to oldest at the bottom, but for multiple Messages on the same day, it sub-sorts those in chronolical order top-down from oldest to newest (that is, in reverse of the primary sort). IOW, the primary sort (based on day/date) is newest-first, and the secondary sort (based on time of day) is oldest-first. Very confusing, and hard to read.
