XML Elves

I am trying to display content in IE. When the page displays content that references SVGs, it converts the SVG into a referenced file entity. The actual HTML markup for the references SVG that is seen when I select "view source" from the HTML page is:

<embed width="600" height="400" type="image/svg+xml" pluginsPage="http://www.adobe.com/svg/viewer/install/" src="https://.../_id_0000040dWHGA016402010GYZ.ent"></embed>

When you view the "src=" attribute value (the file entity), it displays the SVG code, so I know it is actually referencing the SVG, BUT, when viewing the embedded SVG inline in the HTML it displays as a blank scroll box, not as the SVG image. When I disable the "XML Document" IE Add On, it does not display the blank scroll box any more, but instead displays a red "x" as if the content doesn't exist. When I enable the "XML Document" IE Add On again it displays the blank scroll box again. I do have Adobe Viewer installed. I know it is working because I can display stand alone SVGs from my workstation, and I can display the same SVGs (not inline in the HTML) in a different page.

So, my question is:
Is there a setting in IE that makes it think it is supposed to display SVG content as embedded XML text but instead it shows up as a blank scrollable text box (that you can't type anything into)?
- I have coworkers that don't have any problem displaying these same pages, so it makes me think it is some problem with my IE or workstation settings.

Can you reference an SVG as a file entity or is there a problem with doing that?
