Email - New window

This is somewhat off topic, but it's only happening to me on email from
this list, so here goes.

Some of the email I receive on this list is not immediately readable. 
Instead of the actual message text I get a box with a hypertext link
that says "Part 1.1 Type: Plain Text (text/plain) Encoding:
quoted-printable".  I must right-click on these and "Open in a new
window".  This is time-consuming, plus it leaves a folder with a .TMP
extension on my system that I must manually delete.

This started a couple of weeks ago and so far is limited to emails on
this list.  But not all email on this list.  Some senders email are more
likely to have this than others.  I'm using Communicator 4.7 and can't
seem to find any settings regarding this sort of thing.

Am I alone here?
