javascript/css netscap-ism work-around?

Hi,

I apologize if this has been sent to the list before; hwg-style is not 
archived and I couldn't find anything in the FAW regarding this particular 
netscapism javascript/css work-around.

I've got a simple javascript rollover for a left nav-bar that's placed 
using the styled {position:absolute} in a class definition.  The rollovers 
work in seamonkey and in IE, and the css and html validate on the w3c site, 
but when I test Communicator 4.74, I get javascript errors and no rollovers 
(which makes me think it's a netscapism -- grr!). The site's not up, 
otherwise I'd point you to a URL, but code snippets follow.

The rollovers are just aesthetic affordances (I could do it in tables or 
without the graphic elements) but I'm trying to learn the nuances of 
stylesheets and four hours of testing and web searching hasn't helped. 
*Any* advice besides generating an initial browser test would be greatly 
appreciated.

thanks!

from the stylesheet:

.navbar {
	position: absolute;
	left: 11px;
	top:61px
}


from the javascript: (the webmonkey source is acknowledged in the long version)

function WM_imageSwap(daImage, daSrc){
   var objStr,obj;
   if(document.images){
     if (typeof(daImage) == 'string') {
       objStr = 'document.' + daImage;
       obj = eval(objStr);
       obj.src = daSrc;
     } else if ((typeof(daImage) == 'object') && daImage && daImage.src) {
       daImage.src = daSrc;
     }
   }
}


from the html:

<p class="navbar"><a href="./" onMouseOver="WM_imageSwap('home', 
'graphics/nav-home-over.gif');" onMouseOut="WM_imageSwap('home', 
'graphics/nav-home.gif');" onMouseDown="WM_imageSwap('home', 
'graphics/nav-home-down.gif');"><img src="graphics/nav-home.gif" 
width="118" height="37" border="0" alt="home" name="home"></a><br>
