title: How to control the size of pop-up window?
body: <p>I used the following js to pop-up a new window from original window:</p>
  
  <pre><code>oWin = window.open("PServlet?module=LoginHandler","_blank",
  "directories=no,location=no,menubar=no,resizable=yes,status=yes,titlebar=yes,toolbar=no", 
  false);
  </code></pre>
  
  <p>As you can see, I did not set the size or location of new window, But my test results is that the size of pop-up windows on every time was shown irregularly from the same size of original window, sometimes it is half, sometime it is full screen or partial size.</p>
  
  <p>Everybody know what is reason?
  If I wouldn't change the JS, how can I let the pop-up window to be displayed in full screen in every times.</p>
