<h2>wxIEHtmlWin</h2>

The wxIEHtmlWin class is the first example of using a contributed
wxActiveX class in wxWindows C++.  It is still experimental, but
I think it is useful.

<p> Using this class is simpler than ActiveXWrapper, doesn't rely on
the win32all extensions, and is more "wx\'ish", meaning that it uses
events and etc. as would be expected from any other wx window.
