Display word documents in portal content

Hi,

I have some word documents, which i want to display directly in the portal page. To display the documents I have generated a URL for each document and put this URL into an URL iView.

But the problem now is, that it always opens a separate window for the word documents, although I have set the property "Open in portal content" in the iview and "Isolation Method - Embedded" in the portal page.

Does somebody know, which additional settings are needed, to show the documents embedded in the portal page?

Thanks in advance!

Regards,

Lydia
