	No, the reason for that, IIRC, is that for the program to be able to 
interact with the window manager, it has to be launched with pythonw. 
When the program starts to display stuff elsewhere than in STDOUT or 
STDERR, an application launch is somehow triggered (icon appears in the 
Dock), which for some reason enables the user to interact with the 
	Launching a web browser requires no interaction whatsoever with the 
WM, and can therefore be done with python.
