Hi, 
Thanks for your answer. But the problem I have does
not concern group ids, but user ids (or so I believe).
I have made the fix you suggested. Okay so now, my
group id is no longer "None" but "Administrators".
I have :

> ls -al
total 108
drwxr-xr-x   1 Administ Administ        0 Feb 18 11:37
.
drwxr-xr-x   1 Administ Administ        0 Feb 11 17:12
..
drwxr-xr-x   1 Administ Administ        0 Feb 15 15:23
CVS
-rw-r--r--   1 Administ Administ     8008 Feb 18 11:27
isse-xml.tex
> id
uid=500(Administrator) gid=544(Administrators)
groups=544(Administrators)
> emacs isse-xml.tex &

=> When emacs is loaded, he tells me I can't write
over isse-xml.tex...
I'm administrator: rights are rw-r--r--. So I should
have rw- access on the file ! Why can't I write on it
?
