Drop down menu problem IE7

Question

I have a small problem, don't know if you can help at all. I have have upgraded to the latest version of spry and created my spry menu in Dreamweaver CS3. It works great in firefox, but in IE7 the drop down menu jumps up to the top of the browser window, instead of below the menu bar.
When I check using the browser compatibility function in CS3, I get a message "Expanding Box Problem" with the following lines of code highlighted:
<ul>
          <li><a href="testimonials extra.html">Extra</a></li>
          <li><a href="testimonials defender.html">Defender II</a></li>
        </ul>
Here is link to the site, so you can take a look

Any ideas or help would be greatly appreciated ?
regards,

BROWSER HACKS: the hacks below should not be changed unless you are an
expert
/* HACK FOR IE: to make sure the sub menus show above form controls, we
underlay each submenu with an iframe */
ul.MenuBarHorizontal iframe
/* HACK FOR IE: to stabilize appearance of menu items; the slash in float is
to keep IE 5.0 from parsing */
@media screen, projection
     ul.MenuBarHorizontal li.MenuBarItemIE
     display: inline;
     f\loat: left;
     background: #FFF;
