Javascript to force a browser window to a certain size and center itself
Thanks to Gus C in the PowerPoint newsgroup for this trick:
To force a browser window to open at a certain size and center itself on the screen, add this to your HTML (template). Substitute the values you want for width and height.
<script Language="JavaScript">
var width=678;
var height=500;
self.moveTo((screen.availwidth-width)/2,(screen.availheight-height)/2);
self.resizeTo(width,height);
</script>
