Staroffice saving *.doc files as PMN image
 

Greetings all.
Biggest Linux Newbie here. I have a PC running RH7.2 and Star Office. I don't know what's changed but now when I open a word doc and save it (eg opening a mail doc attachment), it automatically saves in PMN image, therefore cannot open the file again.
Any help would be most appreciated.
