Problem with drop down roll over menu

I'm trying to make the text appear as one long line on the pull box for this menu.

When you click the menu item Products, then Cameras,
and the pull out menu appears,
I want to make the items in that pull out menu appear as one long line,
but it wraps to a certain length:

Menu #5    on this page:

http://www.cssplay.co.uk/menus/drop_examples.html

I made the pull out box bigger, but the text still wraps and doesn't display as a long line:

/* controls box lenght for slide out size */
.menu5 li:hover ul li:hover ul,
.menu5 li a:hover ul li a:hover ul {
visibility:visible; color:#000; border:1px solid #ddd; height:auto; background:#fff;
width:15.5em;          <<<<<<<<<<<<<< make the pull out box bigger
}


Which parameter (if any) would stop the text from wrapping?  thanks
