I have the solpart menu on my skin and it renders perfectly everywhere by IE 7.  It works in IE6, and I have a IE specific CSS that loads.  The menu CSS is:

.MainMenu_MenuItem, .MainMenu_MenuItemSel
{
   cursor: pointer;
   color: #666;
   font-size: 12pt;
   font-family: Arial, Helvetica;
   background-color: Transparent;
   text-decoration:none;
   line-height:26px;
   position:relative;
}

.MainMenu_MenuItemSel, div#menuContainer
{
   color:#CCC;
}

The site is www.sqlclr.net if anyone sees what I am doing wrong here I would appreciate any help I could get.  I am a DBA not a web developer, so this is completely foreign to me.  I have tried everything I can find to no resolution of this problem.
