fade option not working with custom CSS properly

[lxxl]

hello,

first off: this is a really great tooltip script! this is exactly, what i've been looking for.

the only thing, i'm wondering about, is, how (or if) it is possible to get the fade option working properly, when using own CSS definitions (and a gif-image in the tooltip's body tag). unfortunately it is not fading at all.

to render this more clearly, here is the code:

PHP Code:

<area shape="rect" coords="14,25,179,91" href="#"
title="cssheader=[TTheader] cssbody=[TTbody] header=[] 
body=[<img src='images/test.gif'>] fade=[on] fadespeed=[0.7]"> 


and

PHP Code:

<area shape="circle" coords="375,56,23" href="#"
title="cssheader=[TTheader] cssbody=[TTbody] header=[hint]
body=[some sample text] fade=[on] fadespeed=[0.7]"> 


and this is the according CSS:

PHP Code:

.TTheader {
    margin: 0px;
    padding: 0px;
    border-top-width: 0px;
    border-right-width: 0px;
    border-bottom-width: 0px;
    border-left-width: 0px;
    border-top-style: none;
    border-right-style: none;
    border-bottom-style: none;
    border-left-style: none;
    font-family: Verdana, Arial, Helvetica, sans-serif;
    font-size: 12px;
    font-weight: bold;
    color: #FF9999;
    font-variant: small-caps;

}

.TTbody {
    border-top-width: 0px;
    border-right-width: 0px;
    border-bottom-width: 0px;
    border-left-width: 0px;
    border-top-style: none;
    border-right-style: none;
    border-bottom-style: none;
    border-left-style: none;
    margin: 0px;
    padding: 0px;
    font-family: Verdana, Arial, Helvetica, sans-serif;
    font-size: 9px;
    font-weight: normal;
    color: #666600;
    font-style: normal;
    line-height: normal;
    font-variant: normal;
} 


any help appreciated.
