Buffering in Wing and IDLE 3

Wed Feb 1 10:17:39 EST 2012

Hi,
I'm using Python 3.2.x with beginners.
If I try the following in IDLE 3, it works as expected :
from time import sleep
import sys
for i in range(4) :
 sys.stdout.write(str(i))
 sys.stdout.flush()
 sleep(1)
but with Wing-101, it write 0123 after the total sleep time.
Why ???
I would prefer to use IDLE but as we are in France, the Python team 
does not seem to be aware that the ~ and others are not available 
on MacOS-X here (probably the same in Europe)...
