3 out of 8 pages do not have the body centered. In the affected pages the body moves 3mm right. This is the css code

#centerbody {
position : relative;
width : 972px;
margin-left : auto;
margin-right : auto;
border-bottom : 10px solid #fffffe;
border-left : 10px solid #fffffe;
border-right : 10px solid #fffffe;
background:#fff;
}

Using a table with 3 columns, table width 972. All pages have 3 columns.
Any ideas?
