i placed red border on submenu's containing element, illustrate menu appears positioned correctly.

any suggestions appreciated.

the issue filter css properties you're setting on <ul> , <a> tags in code. ie9 render gradient backgrounds you, causes set haslayout flag on element internally, causes renderer treat element if had overflow: hidden; , can't override setting overflow: visible; it's not actually css rule, rather way internal rendering engine treat element when processing it. if remove filters filter: none; in override, or don't set them, should see work correctly again.
