It looks like you are missing a needed extension of the current class, you should add this in your your menu.css:
ul#cssmw10 > li > a.current {
background-image: url("../cssmw11_images/paw_f2.jpg");
background-repeat: no-repeat;
border-bottom: dotted 1px #9EA3AA;
color: #430f04;
text-decoration: none;
}
