Layer problem

I used code from a website to center a layer. I then nested a layer in it
for a menu. When viewing in Mozilla and Netscape 7.0 it looks good.

When viewing in IE 6.1 there is a slight empty space above and below the
image.

How do I fix this?

Here is the code and link http://www.ravineco.com/test2.htm

body {
margin:50px 0px; padding:0px;
text-align:center;
}
#Content {
width:660px;
text-align:left;
border:1px solid #333;
background-color:#eee;
margin: 0px auto;
}
#menu {
text-decoration: none;
font-family: Tahoma;
width: 660px;
}

Thank You
