Hi again,
To create an instance of the interface use:
ie = Dispatch('InternetExplorer.Application')
# To get a document and body have to navigate
ie.Navigate('about:')
doc = ie.Document
body = doc.body
body.write('<h1 id=mytitle>Hello there</h1>')
ele = body.all('mytitle')
To catch events see the code in MainWindow.py. It doesn't work because it's
part of a bigger project, but you can see how things work.
Also another really good way of embedding IE is in a wxPython application.
In the wxPython demo application see the file ActiveXWrapper_IE.py

Matthew, thanks.
I had given up on that problem. Given that Mark Hammond seemed to be saying
that what I wanted is impossible, I can hardly wait to try your code out.
Thanks again.
