Okay, the IE7 fix has been released - Superfish is now v1.4.6 (couldn't be bothered saying 1.4.5.1).
Richard, I found that adding -moz-opacity:.999 to the body of the documentation CSS (to fix FF2 Mac) caused the fade-ins not to work in FF3 Mac! They just popped straight to full opacity after the animation time was complete. The only fix I could think of was to do: if ($.browser.mozilla && $.browser.version < 1.9) $('body').css('-moz-opacity',.999); Very disconcerting. Please let me know if the issue is not fixed for FF2 Mac - I neglected to keep a copy to check. Joel Birch.
