Netscape 7.2 (which I use) cannot sort threads by subject line. (by this
I don't mean messages within a thread, which should be in thread order,
but rather, the group of threads themselves)

Of course, since threads are not defined by subject line, this is
understandable,

If I understand what you've written, I disagree: it is clearly a bug and
not "understandable". As you point out, messages w/in a thread should be
in an order consistent with thread ordering. But the relative ordering of
threads themselves is - obviously - independent of threading. One should
be able to order threads however one wants (subject, date, etc.).

Not being able to do this isn't understandable (except as a "whoops!" {8^).
