As I was finishing up the redesign of this site, I did a check in IE8.   Oh No! The pages that used Section-Ex to render the page were messed up.  And the Section-Ex support forum was down for restructuring.   I found a neat little plug in in the Extensions Directory that claimed to improve IE8 compatibility.  A quick download and install and, boom, all was right with the IE8 rendering.  This one goes into my "must install this on all sites" list. 

Get it here, quick. And kiss your some of your IE8 problems goodbye.
