can't hit the link that I can see

[Brigitte]

Hello,

I'm having nested layers, part of the code is:

<span id="idtop" style="position:relative; top:0px; left:
0px; width: 611px; height: 400px; z-index:1; visibility: visible;">
&nbsp;
<span id="id0" style="position:absolute; top:0px; left:
0px; width: 611px; z-index:1; visibility: hidden;">
.... in the this layer a table with a link is included
</span>
</span>

[url]http://www.ttcpratteln.ch/vorstand.htm[/url] (click on a ball to see the
link)


In IE all works fine. In NS6/NS7 the LINK isn't clickable.
Any help is appreciated.

Thanks, Brigitte
