Why does my page work in IE9's IE7 mode, but not in IE7 itself?

Question

I recently went live with our new home page, after heavily testing it in each of IE9\'s browser and document modes (not just compatibility mode, but actual IE7 and IE8

Answer 1

The problem seems to be with the slideshow

Glancing through your script.js file i see this

/*
 * Here is the slideshow code.
 */

 // Screw ie7...
if ( !($.browser.msie && $.browser.version <= 7.0) ){

so i would start my search there, as it seems to ignore IE7 and below..
