title: IFrame Content shows white in IE7 and with IE=EmulateIE7 (Sharepoint)
body: <p>I want to embed my web application inside Sharepoint as a web part. This works great on IE8, IE9 and Firefox - but when I open the page with IE7 I can see only a blank (white) IFrame although the inner content has been loaded. The same webapp opened without the Iframe works perfect - also in IE7.</p>
  
  <p>Same for IE8/IE9 with the META tag:</p>
  
  <pre><code>&lt;meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /&gt;
  </code></pre>
  
  <p>I also can click with the right mouse button on the white area and can display the source code of the page embedded in the IFrame.</p>
  
  <p>My IFrame is embedded like this:</p>
  
  <pre><code>&lt;iframe title="WebApp" frameBorder="0" id="MSOPageViewerWebPart_WebPartWPQ2" style="z-index: 1000" name="MSOPageViewerWebPart_WebPartWPQ2" width="1200px" 
  height="1200px" src="http://webapps/app1/beta.webapp.aspx?ContentAreaHeight=669px" ddf_src="http://webapps/app1/beta.webapp.aspx?ContentAreaHeight=669px"
  &lt;div class="UserGeneric"&gt;No IFRames supported.&lt;/div&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>In Sharepoint it makes no difference if I embed the IFrame manually with the Content Editor webpart or with the Page Viewer webpart.</p>
  
  <p>Can anyone help me?</p>
