How to close the DOS Shell when starting a python script

[m.errami at gmail.com]

Hello all.
I know the question will seem stupid but googling it gives me only
stuff I don't care about.
So the question is the following:
When I start a python script containing a wxApp under windows XP, I
double click , my program opens and a background DOS shell also opens.
Is there any way to prevent the DOS from opening?
What is weird is that when I create a freezed version (an executable),
then the DOS shell doens't open anymore.
Any clues?
Thanks for your help
M.E.
