I'm not entirely sure why David McNab's suggestion wasn't adopted,  
though it appears it would need some tweaks to work with the various  
types of containers we support now. But in general I think the reason  
we never allowed for directly overriding the event is that  
OnLinkClicked just doesn't work like most wxWidgets events and we  
probably need to create our own wrapper event to do this properly.

Anyway, the solution for you is to create an appcomponents directory  
where you have your main application files. Copy the components/ 
htmlwindow.py file to that directory and modify OnLinkClicked in that  
file to do what you want. Alternatively, create an htmlwindow.py file  
in  the appcomponents directory and subclass the HtmlWindow component  
that only modifies the OnLinkClicked method.

The appcomponents directory is checked for components before  
PythonCard looks at PythonCard/components so that allows you to add  
your own components as well as override any of the defaults.
