Spry Horizontal Menu Submenus Won't Appear - Help

Question

OK, I have a Spry Horizontal Menu Bar done through DW CS5. The root menu items work just fine. And the arrow graphics indicating there are submenus are shown, however when you hover over the main menu item the submenus do not appear in browser preview. The spry menu bar is located in the header div above a main content div and a sidebar div (two column layout). Interestingly enough if I drop a new menu bar in the main content div with sample submenus it works fine, so the css file must be ok because they both read off the same css file.
My only assumption is there is something in the header code which conflicts with the submenus and is not allowing the submenus to appear. Unfortunately I can't post it only in a test location as I am reworking an existing website and when I post the new css file it will obviously change the existing website.
But here is some of the relevant code. First the HTML for the section in question.
I very much appeciate any advice.

Move the constructor for the menu bar up to read as follows
<script type="text/javascript">
<!--
var MenuBar1 = new Spry.Widget.MenuBar("MenuBar1", {imgDown:"SpryAssets/SpryMenuBarDownHover.gif", imgRight:"SpryAssets/SpryMenuBarRightHover.gif"});
swfobject.registerObject("FlashID2");
swfobject.registerObject("FlashID2");
swfobject.registerObject("FlashID3");
//-->
</script>
