You can use the following code:
<A HREF="yourfilehere.html" onclick="NewWindow(this.href,'name','800','600','yes');return false"> link here</A>
The 800 x 600 would be the full size resolution that I would use because you are not sure if the user is at 1024 x 768 or 800 x 600.
Another way would be below:
<script language="JavaScript1.2">
<!--
/*

*/
top.window.moveTo(0,0);
if (document.all) {
top.window.resizeTo(screen.availWidth,screen.availHeight);
}
else if (document.layers||document.getElementById) {
if (top.window.outerHeight<screen.availHeight||top.window.outerWidth<screen.availWidth){
top.window.outerHeight = screen.availHeight;
top.window.outerWidth = screen.availWidth;
}
}
//-->
</script>
This is a javascript that should be placed between the head tags of the popup window. It will automatically maximize the window the the users resolution.
Hope this helped.
