Oops! Sorry. I use Python 2.2.2 with Idle 0.8. You wrote:
   t = self.c.read_eager().replace('\r','')
What is 'c'? Is it scrollbar? Is 't' read position of scrollbar? Look at my
code and tell me where I must put it into my code. Please correct my code
and send me back if you can, please. Thanks. Zyziu from Poland.
