Hi,
We had same problem, but solution I was not able to find, so we moved our banner to left side:
<style type="text/css">
.banner {position:relative;
text-align: center;
width:300px;
top:5px;
left:180px;
border:1px
solid black;
padding:0px;
color: #000;
font-size:80%;
padding:0px;
background-color:#00BFFF;}
.smallfont {color: #000; font-size:60%;}
</style>
<div class="banner">
<b>System</b>
</div>
