Maybe a generic error message when it fails to find Python ? Seeing as 
you posted Python code below I lost my motivation to go poking round in 
C++ files. :-)

This is great, it runs fine with Movable Python. (Although I have yet to 
find a machine *without* Python installed to try it properly, I need to 
get VMWare running again.)

When it runs for the first time it prints the following message to the 
console (but works fine) :

    Failed to connect to Pythonwin|System. Error 0

Is this because there is no currently running version of pythonwin for 
it to connect to ?

Anyway, many thanks.
