Why my only page sub menu under "STATISTICHE" button has a white right margin?

Here the site.

Before last upgrade it didn' t happened

WP 3.0.1
Atahualpa 3.5.3
i use wordpress Menu'

Thanks

because you have set a 5px right margin on the toplevel

#menu1 li {
    margin-right: 5px;
}

The submenu's inherit that setting (that is how CSS works)


you need to disable that for the submenu:

#menu1 li li {
    margin-right: 0px;
}

OK STB,
now it works

Many Thanks
