I am having an issue with IE and atahualpa. If you go to http://floridainventoryservices.com/ in IE and on the left widget you will see the Menu pushing out of the border. and on the right widget the whole right side of the border disapears. It works fine in FF. But most of our clients use IE. Thank you for the help.

Have you tried making the right sidebar wider? What widgets are you using? For the left issue this MAY take care of the issue.

#nav_menu-3 {
height: 100%;
}

Thank you that fixed the left side.
