I´ve got the same problem, solved it with adding some IE8 conditional comments in submenu.thtml:
Text Formatted Code
<li>
<a class="drop" href="{menuitem_url}">{menuitem_label}
<!--[if (IE 7)|(IE 8)]><!--></a><!--<![endif]-->
<table width="100%" class="subtable" cellspacing="0" cellpadding="0">
<tr>
<td>
<ul>
{submenu_items}
</ul>
<td>
</tr>
</table>
<!--[if (IE 6)|(IE 7)|(IE 8)]></a><![endif]-->
</li>
Edit: I must remind everyone using this menu, that this css menu is using quite some hacks to render it properly in IE. These make it quite vulnerable, especially when you´ve styled the ul and li items already, or using a reset.css. I would prefer a menu with javascript/ajax to support IE. The Milonic option is not my favourite...
