Display not correct in IE

Hi everyone,

Here's the page: www.ncsmtg.com/documentstest.htm

#navigation gets smaller underneath the Flash file in IE. I'm not sure why. It looks perfect in both Firefox and Opera.

I noticed during editing, when I took out <div id="fourthstep"> and <div id="fifthstep"> plus both of their content, the page looks fine in all browsers. It was also fine when I added <div id="fourthstep"></div>. As soon as I added a paragraph of text in <div id="fourthstep">, #navigation gets pushed in again in IE. What's going on?

Hello pmontesi,
I'm not sure but I think #content {

padding: 0px;
margin: 0 0 0 200px;
width: 600px;
background-color: #fff;
} fixes it for me here.
