Robert,
Yes, you are using MSHTML, but you are getting it from a WebBrowser
control, and I believe that this is the issue. You need to create an
instance of MSHTML.HTMLDocument yourself, and load the content into there.
The document on it's own doesn't require interaction with the desktop (even
though you still have access to javascript events and the like).
You will have to create an IPersistMoniker definition, and then upload
your content through the call to Load. It's a lot of work, but the only way
to untie the document from the visualizer (which is the control).
