menu glitch to fix (jquery/php/css)

Hi Im looking for a very good php/javascript/jquery coder that can fix a little glitch in my menu. My cms uses a menu system from: [login to view URL] and has supersubs implemented as seen here: [login to view URL] However on the sub-sub menus, they overlap in IE (in Firefox and Chrome it is ok... not sure if ok in safari needs checking). You can see this glitch in IE by visiting: [login to view URL] and then hover over Welcome > Sub page 2 > Sub page 3... and then as you hover down you will see the sub page menus overlap as you go down. This is the little glitch that i need fixed - looking for quality work at a reasonable price. Thanks - urgent requirement. Rakesh
