In code view.
Add the following before the head tag
<script language="javascript">
function openWindow() {
newWindow =
window.open("window2.html","subWind","status,menubar,height=400,width=300");
newWindow.focus( );
}
</script>
Then in your document create a link
<a href="javascript
penWindow();">Go</a>
You can adjust width and height.. also if you search around on the internet
you will find all of the window.open parameters, size, position etc.
