auto_view attachment problem in mutt

[bing yu <byu@xxxxxxxxxxxxxx>]

i post again to make my question more clear.

i have installed wvHtml and it works

~/.mailcap 
application/msword; wvHtml --charset=gb2312 %s - | lynx --dump -stdin;
nametemplate=%s.html; copiousoutput
text/html; lynx --dump %s; nametemplate=%s.html; copiousoutput

~/.muttrc 
set implicit_autoview = yes
auto_view text/html application/msword 

the problem is: 

when i attache a MS doc file in my outgoing mail. the doc file can
display properly in mutt(the outgoing mail Fcc to sent mailbox)

but mutt can not display doc when i got doc attachment from others.(as a
matter of fact, this application is really important  to me, say, i want
say what the document my peers sent to me is , and most my fellows us
widows OS ) 

mutt can display all attached text/html/doc file which my peers send to
me from Linux OS. Those attachment except Html file from Window OS, mutt can 
not display automaticly 

anyone can give me any tricks? any suggestion is welcome.
