	// IE6 is really acting up in the left sidebar. For some reason,
	// the first LI with a hyperlink refuses to accept a background
	// color and if one gets set (on rollover or because it's selected)
	// it causes other LI elements to get funky (borders disappear on
	// some, icons disappear on all).
	//
	// The only effective workaround I've found is to put a fake item
	// at the top of the list. By moving it offscreen, we can eliminate
	// the odd rollover effect when the user mouses around, but it's
	// still in the tabbing order, and I can't seem to get it to take 
	// up less vertical space. Floating or absolute positioning solves 
	// the spacing problem but removes the cure.
	//
	// For now, IE6 users will just have to live with a navbar that's
	// a bit lower than it should be.
