Topic: IE scroll bar problem, Firefox is ok

My page is fairly simple, a small table (50 pixels) at the top for a navigation bar.  The rest of the page is left for Simple Viewer.  And I changed the background to be 'transparent' so I can use a background image.

I do NOT want a scroll bar on the right.  In firefox that's exactly how it is, but in IE everything appears a bit larger, and that darn scroll bar appears.

If you view my page you'll see I'm using:
<style type="text/css">
    /* hide from ie on mac */
            html {height: 100%; overflow: hidden;}
            #flashcontent {    height: 100%;}
    /* end hide */

What else do I need?
