<div class="ie6nomore" style='border: 1px solid #F7941D; background: #FEEFDA; text-align: center; clear: both; height: 75px; position: relative;'>
<div class="close" style='position: absolute; right: 3px; top: 3px; font-family: courier new; font-weight: bold;'>
<a href='#' onclick='javascript:this.parentNode.parentNode.style.display="none"; return false;'><img src='http://www.ie6nomore.com/files/theme/ie6nomore-cornerx.jpg' style='border: none;' alt='Close this notice' /></a>
</div>
<div style='width: 640px; margin: 0 auto; text-align: left; padding: 0; overflow: hidden; color: black;'>
