thanks for the answer. I've searched a bit with google, and i've found 
that web page:

http://www.maubi.net/~waterson/mozilla/journals/2000-11.html

It is said: "[..]if there was an equivalent to __declspec(novtable). Turns 
out that there sort of is: #pragma interface."

Do you think that this pragma can help ?

thank you
