i'v logged into your website.
and activated multimenu05 (you can see it at the bottom of the index's page).
can you send me your theme's folder ? (maybe create an ftp access to theme's folder only ?)
i would like to see which operations you made on the theme.
i'll try to insert this menu into the theme myself, and will compare the result.
{alt}'s tag works on the block (mm05) at the bottom of the page (look at home's link).
