I have had similar experiences with IDLE on both XP and Ubuntu 8.04 and
as a result I use IPython as much as possible. On XP I would recommend
that you install Python(x,y), 2.1.9,
http://www.pythonxy.com/foreword.php
which includes IPython(0.9.1) and IDLE(1.2.2) as well as many other
useful programs.
The example you gave runs under IPython with the command
run -i programname.py
and gives a plot which can be accessed independently of the IPython
shell. In other words you can execute commands in the shell while the
plot is still on the screen.
Hope this helps
Richard
p.s. I, like you, would still be interested in knowing why IDLE crashes
when a .py script is run twice.
