heading

[Nicolas Constans]

Hi everybody,

I have customized my section title in the following way :

\renewcommand{\thesection}{\Roman{section}.}

Thus I replace e.g.
3.2 Blabla
by
II. Blabla

and I'm happy. The problem is that in the heading at the top of the
page, I have now:

II.. Blabla
(two dots).

Do you know a way to remove such a behaviour?

Thank you,
        Nicolas.
