Sorry All. I'm not home where I would post the file on my website. It isn't very exciting (pun intended) mostly just the audio bandwidth specs

That is interesting. I usually get attachments from mailing
lists. I use Thunderbird and don't think I have done anything to
block attachments from this list. I have perhaps a year's worth
of posts in the INbox, none show attachments. I looked at the
posts supposed to have attachments and see no sign of any. So,
what is different? Are you reading from the web site or from a
mail client?
