There are two ways to view attachments in Mutt.  In some 1.5 version,
the default was to display text attachments as text.  I believe this
corresponds to the behavior of the default [enter] key binding.

The usual solution is to use the setting:

  auto_view text/html

The default binding of <Return> in the attachment screen is to the
function 'view-attachment', but I believe there's a second function
that either forces or does not force text attachments to be viewed as
text.  I can't recall the specifics, but I would suggest searching the
Mutt manual for HTML, and it'll probably turn up.

You may need additional bits in your mailcap entry.  The default on my
system for msword is this:

$ grep msword  /etc/mailcap
application/msword; soffice --nologo --writer '%s'; edit=soffice --nologo --writer '%s'; test=test -n "$DISPLAY"; description="Microsoft Word Document"; nametemplate=%s.doc

I'd check whether Mutt has $DISPLAY set in its environment. One way to
do this is to have your muttrc set a local mutt variable, and then ask
Mutt what it is.  Something like:

set  my_display=`echo $DISPLAY`

Then in Mutt, use the colon command:

:set ?my_display

To see what it is set to.
