title: Best way to open browser popup window containing ExtJS grid
body: <p>In our <code>ExtJS</code> application, we have some menus and a tab panel. Clicking on a <code>menuItem</code> opens a grid.</p>
  
  <p>we have a requirement where user can open a display containing a grid in any of the two modes:</p>
  
  <ol>
  <li>Inline - Grid will open as a tab item in the <code>tabpanel</code>.</li>
  <li>Popup - A new browser window is opened using <code>window.open</code> and whole
  ExtJS library is loaded first and then the grid is loaded. <strong>Popup as browser window is to facilitate multiple monitors</strong>.</li>
  </ol>
  
  <p>So the problem here is whenever we open a popup window ExtJS library is needed and it is taking up a lot of memory in IE.</p>
  
  <p>Is there any other way we can load a browser window popup with ExtJS grid without loading the whole ExtJS framework?</p>
  
  <p>Or any other idea are most welcome, as we are really facing a lot of memory issues in IE and users are not willing to use chrome.</p>
  
  <p>Thanks in advance.</p>
