This is basically the only reason that this happens, and is something
that most people learn not to do the hard way (myself included). Rule of
thumb: if you are writing to a mailing list, compose a new/blank e-mail
to the list address.
If you click reply, and aren't sure what you're doing, you'll end up
screwing up threading for other people that use threaded e-mail readers,
including Thunderbird and others that don't care if the "Subject:"
header changes, but stick to the "In-Reply-To:" header. This sort of
thing falls under thread-hijacking, though it's a lot more subtle example.
