Problemi con tool tip

[hankie]

guardate questa pagina:

http://www.theinvaders.it/the_inv_htmlv1/home.html

andate sui quattro quadrati grandi affiancati sul lato destro della pagina, sul prima a destra ho cercato invano di applicare dei tooltip, ne ho provati di tutti i tipi, questo e' l'unico che riesco a fare funzionare un pochino ! ma non troppo....

come avete potuto vedere il tooltip applicato e' completamente sballato, non sono come disposizione rispetto al mouse, ma anche come dimensione in se, infatti, non capisco il perche', sto tooltip esce dalla pagina e crea uno stano errore, mi riferisco a quella sorte di trascinamento che appare sulla destra del tooltip.

Ragazzi fatemi capire cosa sbaglio !!! ci sto impazzendo !!!


Questo e' il Javascript linkato dalla pagina:

var dom = (document.getElementById) ? true : false;
var ns5 = (!document.all && dom || window.opera) ? true: false;
var ie5 = ((navigator.userAgent.indexOf("MSIE")>-1) && dom) ? true : false;
var ie4 = (document.all && !dom) ? true : false;
var nodyn = (!ns5 && !ie4 && !ie5 && !dom) ? true : false;

var origWidth, origHeight;

// avoid error of passing event object in older browsers
if (nodyn) { event = "nope" }

document.write('<div id="tipDiv" style="position:absolute; visibility:hidden; z-index:100"></div>') 

e cosi lo richiamo dal link:

<table>
                    <tr>
<td>

<a href="home.html" >[img]picsbn/00bn_prw.jpg[/img]

</td>
<td><a href="home.html">[img]picsbn/00bn_prw.jpg[/img]</td>
                        
                    </tr>

        
            
</table> 

Cosa sbaglio ????


ps. anche variando var offX= 0; var offY= 0; non cambia molto !

niente raga????

Ps. ho provato sotto windows ! funziona bene ! quindi il problema lo fa solamente con i browser di mac!!!
