100% widths backgrounds in Juno webmail client?

Having trouble getting 100% background widths to show up in the Juno webmail client in ie6 and ie7. I've got all my hotmail 100% width fix in place, but nothing seems to work.

Current code:

<!doctype html>
<html>
<head>
<title>Title goes here</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style type="text/css">
    /* Begin Hotmail 100% width fix. More info: http://bit.ly/96MPFE */
    .ReadMsgBody { width: 100%;}
    .ExternalClass { width: 100%; display: block !important;}
    /* End Hotmail 100% width fix */
</style>
</head>
<body bgcolor="#FAF0C4" leftmargin="0" topmargin="0" marginwidth="0" marginheight="0">

<!-- Begin Wrapper Table-->
<table width="100%" border="0" cellpadding="0" cellspacing="0" bgcolor="#FAF0C4">

etc.
