I have tabbed divs using z-index CSS and Javascript. I got the code,
tab_webfx.css and tabpane.js, from an online example. It works fine
using Firefox and Safari but on IE the images I have in the divs
disappear. They initially are shown but when IE finishes loading they
disappear.

Note: my CSS file is a bit messy and I need to clean it up, i.e.
remove what I am no longer using.
