Need help with IE extending past 100% of browser

I'm trying to get my page to use the full height of my screen 100%. I was able to get it to work fine in Firebird and Opera, but IE extends past the browser window forcing a vertical scrollbar, even tho there is not content to scroll to. Somebody please help
