Weird CSS menu error in IE6

So I got this menu to work well with style and the hover method works in IE6, but when you hover over the appropriate link, the hidden hover section only appears in one location and doesn't come out where the actual link is.

Heres the CSS:

.menu{
font-family: arial, sans-serif;
width:100px;
height:100px;
position:relative;
font-size:10px;
margin:5px 5px 60px 5px;
z-index:100;
}
.menu ul {
padding:0;
margin:0;
list-style-type: none;

width:100px;
height:180px;
}
.menu ul li ul {
visibility:hidden; position:absolute; height:0; overflow:hidden; top:0; left:85px;
}
.menu ul li {

}
.menu ul li a, .menu ul li a:visited {

.menu table {
