Displaying text over image in IE

[Norm]

Hi,
I'm trying to create an HTML page that displays an image and will display a small text at the location the mouse is clicked. I've gotten it to work with Firefox but am unable to get it to work with IE.

After I determine the text I want to display (its in NamesList[]) at the clicked location I use the following Javascript code:

   	  var aDiv = document.createElement('div');
        aDiv.setAttribute("id", LayerNm + divCnt++);
        // Display the name at the upper left of rectangle given in NamesList[]
        var absPt = relToAbs(NamesList[ix+dX], NamesList[ix+dY]);  // get absolute point location
        aDiv.setAttribute("style", 'position:absolute;left:' + absPt.x + 'px;top:' 
                                    + absPt.y + 'px;font-weight:bold;color:cyan');
        aDiv.appendChild(document.createTextNode(NamesList[ix+dName]));	
   	  aDiv.onmousedown = myMouseDown;  // set for new div
   
        imgDiv.parentNode.insertBefore(aDiv, imgDiv);  // works!!!

Definitions from other parts of code:

         imgDiv = document.getElementById('Image');  // set global one time here
   ...
<CENTER><IMG SRC="1990_Reunion-300_ED1.jpg" HEIGHT="96%" ALT="1990 Reunion" id="Image"></CENTER>
   ...

Works in Firefox, but not in IE.
Is there code that will work in both browsers?
Is there code that will work in IE that I can chose if in IE?

Thanks,
Norm
