3 column liquied layout using floats: a: element slightly "pushed in" by float divs

Hi,

I have a 3 column layout. My code is below, but first let me explain. I'm using IE 6 on WinXP. It appears to be an IE problem only. I use three divs, the left and right use floats. The middle div looks like the outer two are pushing in the link color. It's hard to explain, so I posted it below. See for yourself. Thanks!

#navlist {


margin-left: 260px;
margin-right: 260px;


}
#navlist2{
float: left;
top: 93;
left: 10px;
width: 250px;
margin: 0;
}
#navlist3 {
position: absolute;
top: 93;
right: 10px;
width: 250px;
float: left;
}
#navlistDown {
width: 250px;
float: left;
margin: 0px;
}
#navlist ul, #navlist2 ul, #navlist3 ul, #navlistDown ul {

padding: 5;
font-family: Arial, "Century Gothic", "Futura Bk BT";
font-size: 14px;
background-color: #cde;
margin: 5px 0 0 0;
list-style-type: none;
border-top: 1px #000 solid;
border-left: 1px #000 solid;
border-right: 1px #000 solid;
text-decoration: none;
text-align: left;
word-spacing: .25em;
letter-spacing: .05em;
text-transform: uppercase;


}

#navlist li, #navlist2 li, #navlist3 li, #navlistDown li{ margin: 0; }
#navlistDown a{
display: block;
color: #000;
font-family: "Trebuchet MS", "Futura Bk BT", Arial;
width: 99.99%;
background-color: #dbf;
border-bottom: 1px #999 solid;
text-align: left;
text-decoration: none;
padding: 4;
font-style: normal;
font-size: 12px;
text-transform: none;
}

#navlist a, #navlist2 a, #navlist3 a {
