IE 5.0 leaves Top padding

I am testing my newer version of my site through browsercam and IE 5.0 is giving me a margin/padding for the content area of the page as shown here: http://www.browsercam.com/public.aspx?proj_id=11513

View the first picture of the screen shots and you will see what I mean or the original page here: http://www.techsatcomputers.com/index5.htm

Does anyone have any ideas whats going on ?

Here is the style I have used for the content area:

#middlebox {
	margin: 0 160px;
	white-space: normal;
	border-left: 2px solid #000;
	border-right: 2px solid #000;
	padding: 10px;
	background-color: #FDFDE9;
	color: #820;
}
