Re: [Py2exe-users] issue with processing module

[Greg M. <gtm...@gm...>]

Hi Michael,

That's exactly what was happening. Turns out that the processing
module has a function to handle parsing sys.argv for 'frozen'
applications:

if __name__ == '__main__':
    processing.freezeSupport()

And now everything works great. :) Thx for the pointer, I'm not sure I
ever would've stumbled up on that otherwise.
