I have done a lot of research trying to solve this issue, and I cannot find a solution. I'm hoping someone here can provide some insight.

The site: www.lifelinepilots.org/new_site/Home.html

The problem: In Internet Explorer, the sidebar images won't expand to equal the varying page height throughout the site. I have set the image height to 100%, and the body height to 100%. The bar stretches to equal the page height with no issues in Firefox, Safari, and Chrome, but not in Explorer. What could be going wrong?
