First of all, congratulation for this wonderful theme + support.
I was not able to find the solution - even with upgrading to 3.5.3 - to my problem : in (only) one page sub-menu (see www.voilesdantan.org - menu "Association AVAL" above header image) the grey field is limitad to the lenght of the page-title.
The effect is different in FireFox (default browser), IE7, Chrome.
But for all 3 browsers, the effect is not visible in category sub-menus (see menu "Activités" below header image).
Could you please help me ?
Many thanks in advance,
