Fix for disappearing or overflowing primary menus

As in most fixed-width themes, if you have several tabs for a primary menu (most commonly seen in the user profile page, below user name), those tabs exceeding the content area will dissappear from view or overlap the right menu.

Just add the following to your style.css file:

ul.primary {
	white-space: normal;
}

ul.primary li a {
	border-bottom-style: solid;
}

Those styles are predefined in modules/system/system.css, but it´s safer to overwrite these attributes here than to change the style in a core document. Some may prefer not to add the border-bottom-style: solid; attribute. It´s a matter of taste.

Cheers.
