Hiya Mitch,
You could try adjusting the left margin for the menu in menu.css:
ul#cssmw {
background-image: url("../cssmw_images/bg.jpg");
background-repeat: repeat-x;
cursor: default;
height: 30px;
list-style-type: none;
margin: 0 0 0 50px; /* Try adjusting the left margin here e.g. 50px */
padding: 0 0 0 0;
}
