Hi Olivier,
AFAIK, IE can only apply one filter at a time, so when you apply the
PNG fix that's your one filter used and then Superfish's opacity
animations will not work after that. That's why when you change the
code so that the PNG fix is applied after the animation it works for
that first time but not subsequent times. A workaround could be to
avoid fades for Superfish and just animate the height instead:
$('ul.nav').superfish({
animation : { height : 'show' }
});
Hope this works.
Joel Birch.
