Python script freezed on Window DOS terminal

[hce]

Hi,

I am running Python and a script on XP DOS terminal, the script
build.py printed out messages on the Terminal, then asked for an input
of numbers. But, I pressed a key, nothing came in DOS terminal,
Eventually, no key active and seem the DOS terminal is freezed. I
could not even terminate the terminal by Ctrl-C or Ctrl-D. The same
script was running fine on linux or Cygwin terminals. Any thoughts
what was the problem?

Thank you.

Kind Regards.

Jim
