Nothing in particular. However, experience has taught me
to consider Cygwin bugs when porting to Cygwin...

Anyway, I just found a difference between Python 2.2.3
and 2.3 after starting IDLE.

Under 2.2.3:

$ ps | fgrep python
     3308    1400    3308       3092    0 19695 
11:57:56 /home/jt/src/python-2.2.3-2/python

Under 2.3:

$ ps | fgrep python
     2244    1400    2244       2864    0 19695 
12:02:57 /usr/bin/python2.3
      700    2244    2244       3592    0 19695 
12:02:58 /usr/bin/python2.3

Note one python process under 2.2.3 and two under 2.3.
This may explain why IDLE works under 2.2.3 and not.

Were there major IDLE changes between 2.2.3 and 2.3?
If so, what?
