We found a minor error in the CT_RN theme thanks to Bushwhacker.  The change only occurs in the style.css.

Find in the style.css

#span1{float:left;background:url('../images/nav_left.jpg') no-repeat;height:28px;padding:4px 0px 0px 10px;color:#fff;} #span2{float:right;width:4px;background:url('../images/nav_right.jpg') no-repeat;height:28px;}

Replace With

#span1{float:left;background:url('../images/nav_left.jpg') no-repeat; height:28px; padding:4px 0px 0px 10px;color:#fff;} #span2{float:right;width:4px;background:url('../images/nav_right.jpg') no-repeat;width:6px; height:28px;}
