Thank you both (Alf and Duncan) for your comments. I answer Duncan's 
questions interleaved:

Nothing happens and no error message shows. The disk head stepper makes 
a brief attempt at something then goes silent and that's it.

Same thing: Nothing happens

Same thing: Nothing!

python.exe from the command line works all right in a DOS window. The 
problem must be with  idle.pyw. I tried the old idle.pyw (2.4) with the 
new python.exe. (2.5) and that didn't work either.
What is the bit bucket? If I had a clue, I could go from there. What 
puzzles me is that version 2.4 has been working fine and one wouldn't 
think that the changes from 2.4 to 2.5 would be so extensive as to cause 
a major malfunction. For the time being 2.4 works fine. I'd much prefer 
2.5, though, because it includes the image library (PIL), whereas 2.4 
cannot even use it.
