No, it is a listing of the constructor for the class, not a snippet of 
code showing how to use it.  So the self parameter should be removed 
because what you need to pass to the constructor is a parent window for 
the html control, that is how similar things are shown elsewhere in the 
book.  (The confusion you are having is that in the context of using the 
class the parent window is often called self because you are creating it 
in the constructor (or __init__) of the parent window.)

Which version of wxPython do you use?  There was at one time a bug 
related to tab traversal of form controls, etc.

How do you load the initial page?  I don't use this control very much 
myself but I think that if you are loading from a string or a stream 
then there is no context for IE to use to figure out how to find a 
relative link.  If you instead load the initial page with LoadURL() then 
I think it should work.
