Need help please with layering issue

Hi Everyone,I have a page in Lectora where I have several images and text boxes. Just to give you a visual, think speech bubbles and images of people. Now I've added an external html object where I load an external swf and want to ensure this flash object appears on top of everything else.For the external html code, it's this:

What I tried to do was use a top level div where I could set the z-index to ensure it appears on top.The file definitely loads, but it just doesn't appear on the top most layer.Any thoughts?Thanks,Brook
