Sliding door menu - first item at different position

[Damien]

I am using cufon-yui.js 1.0.9 with WordPress 2.9.1: http://www.food4thought.ie/
The horizontal menu looks fine in IE8, FF3.6, Opera 10, Chrome 4 and
Safari 4.

In IE6 and IE7 (and IE8 in Compatability Mode) the first item in the
menu is higher up than the other 4 menu items.
I had a IE specific CSS file that only succeeded in moving the text
down to the correct level but not the menu tab.
#foodmenu li.page-item-19 {
position: relative;
top: 22px;
}

Anyone any ideas?
I tried to ignore this but my client and a number of her customers are
still using IE6.
