/*

Son of Suckerfish CSS based dropdown menus, 
For more information see:
http: //www.htmldog.com/articles/suckerfish/dropdowns/

Adds the sfhover class to elements in IE 5.5/IE 6 and other browsers
that do not support the CSS :hover pseudoclass.

See navigation.css for the code that actually controls the
hover state of the menus.
