Hi Maxim!
I'm not a curses expert and I don't know why this is happening, but maybe
these suggestions will help:
1. Have you read the tutorial Curses Programming with
Python<http://www.amk.ca/python/howto/curses/>?
I found it very helpful.
2. Try using curses.addstr to print text (including colors) instead of
'print' or 'sys.std*'. Examples are in the tutorial.
3. curses.wrapper is nice, takes care of initscr and friends.
4. Check out the Python curses demos,
here<http://svn.python.org/projects/python/trunk/Demo/curses/>or in a
Python source tarball.
5. Bli Kesher, you can get the color codes from terminfo without
running 'tput' (but you don't need them when using curses.addstr):
curses.setupterm() # not needed if you call curses.initscr()
curses.tparm(curses.tigetstr('setaf'), 0) # same as commands.getoutput('tput
setaf 0')
Hope I helped,
Ori.

Shalom people,
I'm new on this list, and to python in general.
Fun with python to us.
I'm attaching my sanity checking script (which in the mean time doing
it's job perfectly - getting me insanse :)
The lines for error don't print with CR/LF but only with LF; I
susspect curses is to blame but I have no experience with it and
haven't found what proper switches/flags/objects I need to pass to it
to make it work like expected.
