title: How to set overflow:hidden for dojo's dialog box
body: <p>I'm using a dojo dijit dialog box to popup data for the lightbox effect.  </p>
  
  <p>The problem is that dojo dynamically changes the style attributes of "containerNode", so that if the box is bigger than the browser window a scroll bar appears.  It sets "overflow:auto" dynamically.</p>
  
  <p>I know this makes sense to do, but I want to override this and force the user to open up the browsers as the modal/lightbox looks really bad otherwise.</p>
  
  <p>How can I change this behaviour?  Sample code would be helpful!</p>
  
  <p>Thanks</p>
