title: Dijit.Dialog 1.4, setting size is limited to 600x400 no matter what size I set it
body: <p>I'm trying to set the size of a dijit.Dialog, but it seems limited to 600x400, no matter what size I set it.  I've copied the code from dojocampus and the dialog appear, but when i set the size larger, it only shows 600x400.  Using firebug and selecting items inside the dialog, I see that they are larger than the dialog, but don't show correctly. I set it up to scroll, but the bottom of the scrollbar is out of view.  In firebug, I've check the maxSize from _Widget and it is set to infinity.  Here is my code to set the dialog.</p>
  
  <pre><code>    &lt;div id="sized" dojoType="dijit.Dialog" title="My scrolling dialog"&gt;
          &lt;div style="width: 580px; height: 600px; overflow: scroll;"&gt;
  </code></pre>
  
  <p>Any suggestions for sizing the dialog box larger?</p>
