[jQuery] [tooltip] Fade on IE

[jQuery] [tooltip] Fade on IE


Hi, I am using and modifying the sample demo page and have a error on
IE:
Using:
$(function() {
    $('#pretty').tooltip({
        track: true,
        delay: 0,
        fade: 500,
        showURL: false,
        showBody: " - ",
        extraClass: "pretty",
        fixPNG: true,
        left: 120
    });
});
The fade effect on IE causes that the image shadow.png appears black
on border for a while, fade effect is too uggly, firefox and safari
works fine. Now I have to set fade=0 only to support IE7.
Is there a way to use it?
Thanks.
