many times. I do NOT trust that they wait for the page to be completely
loaded. The only thing I've done that works consistently is to set my OWN
"Page done" flag AFTER the closing <HTML> tag.

I would do something like this <body >
and have this script at the top
<script>
var links_enabled = false;
function enableLinks() {
links_enabled = true;
}
function Popup(file,width,height)
{
var topX = (screen.width - width)/2;
var topY = (screen.height - height)/2;
if (links_enabled) {
popup = window.open(file, "Popup", "fullscreen=no, toolbar=no,
status=no, menubar=no, scrollbars=yes, resizable=yes, directories=no,
location=no, width="+width+", height="+height+", left="+topX+", top="+topY)
popup.focus();
}
return false;
}
<script>
