Hi. I think a workaround is to modify contents of /usr/share/applications/ooo645writer.desktop in order to add application/msword to it.
See details in bug #288683 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=288683) Hope this helps. Best regards, -- Olivier BERGER <[EMAIL PROTECTED]> Ingénieur Recherche - Dept INF INT Evry (http://www.int-evry.fr/) OpenPGP-Id: 1024D/6B829EEC
