[jQuery] [Superfish 1.4.8] changing position of folded out menus

Hi!

First of all I'm very sorry to ask, but I couldn't get it working
whilst spending hours on this.
I changed the ling-height of the .sf-menu from 1.0em to 2.5em.
Now the folded out submenus appear in the middle of the menu bar.

=========================
.sf-menu {
line-height: 2.5em;
}
=========================

Simple question: How can I change the position of the folded out menus
so that they appear directly under the menu bar, not in the middle of
it?
Like in the standard example of the superfish menu?
