Could you please try it and let me know if something wrong?

P.S. You may notice issue with new name on screenshot, I ran it with Python 2.7.* so maybe this is a reason, anyway I'm going to investigate it later.
P.P.S. I've put black background to keep it readable no matter what colour background is used in console.
