Grouping problem (thread hierarchy screwed up by OE6)

Outlook Express 6
Windows XP Pro SP-2

In one thread, I thought that a poster has mistakeningly submitted their
post as a reply to my post (which was a also a reply). Their reply showed
up indented and underneath my post. However, after looking at Google Groups
and also checking the chaining in the References header in each post, the
other person did not reply to me but to the original post (mine was a reply,
not the original post). What should've been:

originalpost
myreplypost
theirreplypost

instead looked like:

originalpost
myreplypost
theirreplypost

I and the other respondent were neither the original poster. Looking at the
Message-ID and References header in each post:

Original post
Message-ID: . com

My reply to the original post
Message-ID:
References: . com

Their reply
Message-ID:
References: . com
My Message-ID is not included in your References header. Just the
Message-ID for the original post.

My reply to your post
Message-ID:
References: . com

Your Message-ID gets chained in References.

Their reply to my post
Message-ID:
References: . com


The References chain still looks good.

For some reason, your post looked like it was a reply to mine although the
References header shows that is should not. I also noticed that the
original post is missing from the original server which I used for my first
reply and the second server I used to see your reply (and make my second
reply). Both AIOE and Teranews are missing the original post, so I suspect
OE is using the Subject header to group the message - but it should not.

Time to review alternate NNTP clients again. Thanks for responding because
it helped me find that OE doesn't correctly group the threads. It's
peculiar because this is the first one that I've seen where OE doesn't group
properly by the References header.
