I'm interning for an NGO in India and trying to fix their website, including updating their menu so it's not the last item on the page to load, and it's centered on the screen. Everything works well enough but when I try out my new menu in IE6, I get this weird error where the content below the menu is padded an extra 30px or so and the material in the right-most drop down appears on the far left of the screen, always visible. When I drop down the rightmost link ("Publications") the content appears both in the correct location and in the same spot on the far left of the screen, and changes color when I hover as well. It's tough to describe, so it would probably be best if you took a look:

visit http://sevamandir.org/a30/index.htm in your Internet Explorer 6 browser to see for yourself. I really appreciate your help. Also I'm using a 1000px wide monitor, if there's more hijinks going on outside that space I'd like to know about that too.

Here's the relevant code:

in the html head:

<script>
sfHover = function() {
var sfEls = document.getElementById("nav").getElementsByTagName("LI");
for (var i=0; i<sfEls.length; i++) {
    sfEls[i].onmouseover=function() {
        this.className+=" sfhover";
    }
    sfEls[i].onmouseout=function() {
        this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
    }
}
}
if (window.attachEvent) window.attachEvent("onload", sfHover);
</script>

text surrounding the menu - the menu is simply

<ul id="nav"><li></li></ul>

etc.

<!--begin catchphrase-->
    <div style="float:left; height:27px; width:520px; margin:0px; font:16px Arial, Helvetica, sans-serif; font-weight:bold; color:#769841;">

    </div>

    <?php include("menu.php"); ?>

    </div><!-- end header -->
