[Samba] MS Word unable to sense file opening by other users

[Leonardo Boselli]

I observed this behaviour with frontpage.
In that case frontpage refused to create new files ...
since most of pages created with that program are faulty, i conidered this 
bug an useful feature, since forced two people that used frontpage and 
complained that their pages were slow to load and did not appeared 
consistently on every computer to switch to a different page-editor.
BTW: i think the problem arise from the fact that some exdended 
attributed present under windows are not present on *ix standard file 
sistem.
