А может и вправду дело в стилях..
<style type="text/css">

#scroller-header a {
	text-decoration:none; 
	color:#867863; 
	padding:0 2px;
}

#scroller-header a:hover {
	text-decoration:none; 
	color:#4b412f
}

a.selected {
	text-decoration:underline !important; 
	color:#4b412f !important;
}

#scroller-header {
        float:left;
        border: black solid 2px;
	width:800px;;
	height:40px;
	padding:35px 0 0 15px;
	font-weight:700;
}

        #scroller-body {
        border: red solid 2px;
        float:left;
        width: 800px;
        height: 300px;
	padding-bottom:30px;

}

#mask {
        border: green solid 2px;
