Q490 Is it possible to determine the pixel coordinates of the mouse in relation to the screen when passing over a link, and then open a popup window in that position?

<script language="JavaScript"><!--
function showWindow(e) {
    var x=y=0;
    if (e != '') {
        x = e.screenX;
        y = e.screenY;
    }

    myWindow=window.open('apage.html','windowName',
        'width=100,height=100,screenX=' + x + ',screenY=' + y + ',left=' + x + ',top=' + y);
}
//--></script>

<a href="#" onMouseOver="if (window.event || document.layers) showWindow(event); else showWindow('');"><img src="picture.gif" width="200" height="200"></a>

<p>

<a href="apage.html" onMouseOver="if (window.event || document.layers) showWindow(event); else showWindow('');">A text link</a>
