[Mailman-Users] Mail archives threads are getting mixed up

[Casey Ajalat]

I've recently setup mailman for the first time and the install went
flawlessly.  However, after starting a few mailing lists I noticed that
some of the mail in the archive is getting mixed up under different
threads.  i.e. If two messages each with a different topic were sent and
others had to reply to either of those then in the archives I would see
something like this when sorting by threads:

* SUBJECT A
  * SUBJECT B
    * SUBJECT B
* SUBJECT A

Furthermore, clicking on each of the messages above (3rd line for example)
reveals the content of the second line (the line above it).  This all
started to happen when I approved two postings at the same time on a
moderated list.  I don't see this behavior on the non-moderated lists.

Second question:  Is there a way I can wipe the archived HTMLs and then
have the system rebuild them?  i.e. can I just delete the files:

archives/private/tb/1999-October/author.html
archives/private/tb/1999-October/date.html
archives/private/tb/1999-October/subject.html
archives/private/tb/1999-October/thread.html
archives/private/tb/1999-October/index.html

and have the system rebuild them?  Other ideas???
