--oJAv8lSwuaQsYd0G Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable [Format recovered--see http://www.lemis.com/email/email-format.html] Still wrapped output. This is painful to recover, and I tend to lose interest when it continues.

It's better to have your own partition.

This one doesn't match the other. Are you still getting the message? Greg -- When replying to this message, please copy the original recipients.
