	// HACK: safari 1.3v312 has a nasty bug which causes the navigation images to be hidden
	// behind the colorbar divs.
	// HACK: stupid safari hack: we change a property of the navigation div to force a reflow of that
	// div, which fixes a bug in safari in which the navigation images don't show up on a page refresh.
	// we choose a property that we're not actually making use of. In this case, we use the 'color'
	// property. Since there is no text in the navigation div, this won't hurt anything.
	//var elem = document.getElementById('navigation');
	//elem.style.color = 'red';
