You can fix this issue by using CSS to force all your margins, padding, etc to zero. Used to drive me crazy a few years ago on a site I was working on

<style type="text/css">
<!--
Body {
	margin-top: 0px;
	margin-right: 0px; 
	margin-bottom: 0px;
	margin-left: 0px;
	padding-top: 0px;
	padding-right: 0px; 
	padding-bottom: 0px;
	padding-left: 0px; 
	border-top-width: 0px;
	border-right-width: 0px;
	border-bottom-width: 0px;
	border-left-width: 0px;
}
-->
</style>

Good luck!
