[Tutor] Unstable IDLE

[Timo Smieszek]

Hi

I use Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) on a 
Macbook Pro (Mac OS X 10.6.7).
Whenever I want to open a new window in the IDLE or whenever I work with 
.py file within the IDLE, it crashes either immediately (in case of 
opening a new window) or after a short time (in case of opening an 
existing file).

I already installed Python a second time, but this also does not help.

Has anybody an idea how to fix this problem?

Thanks and all best

Timo
