DIV problem with IE, help needed

Hey guys,

first of all, i know my css and html are messy, but i’d like to have things working before cleaning unused code.
The problem i’m facing is IE not showing the page as i want to, but FF and Opera do so. I’ve all the latest versions of these browsers.
URL is http://www.huizehoog.nl/index.php

As you can/might see the inline frame in IE is shown below the space it hould be. Doing so it also stopped showing the original content of this page, which is viewable in FF and Opera. Both of them also show the header as it is supposed to be.

I know it must be some kind of div problem or something in my css file, but i can’t figure it out.
Can somebody help me out?

Thanks in advance!

Looks like IE7 can’t find the room to fit the autoviewer in.
You could try reducing the inner borders on the two menu items until it fits and setting the iframe page background to black.
Out of interest why use an iframe?
