How come? IWebBrowser2::get_Parent gives you the parent Document object.
Query it for IServiceProvider and call QueryService(SID_SWebBrowserApp)
to get an enclosing IWebBrowser2.

BeforeNavigate2 fires for URLs like vbscript: and javascript: that don't
actually cause navigation and thus don't destroy frames. Also, the user
can hit Stop button at any time. If she does so between BeforeNavigate2
and NavigateComplete2, the original page stays untouched, frames and
all. But if she hits Stop after NavigateComplete2, she gets a blank page
or Navigation Aborted error page, depending on the settings. Either way,
the frames are gone.
