I am new to Python and I have installed the 64-bit version 3.4.1 using the .dmg installer from the Python website, and when I start IDLE and try to create a new file, IDLE crashes and quits. Same thing happens when I try to load a Python file using the "File > Open" option.
I am running Mac OSX 10.6.8 Snow Leopard on an iMac Intel Core i3 21.5in, and the Python version is 3.4.1.
IDLE itself seems to work, it's only when I try to create a new file or load a file that it quits.
Just to add, the create new file opens a small blank window with no header, which then causes both windows to become unresponsive. I would include a screenshot but I don't have enough rep :(
EDIT: I just installed an older version of Python (3.3.5), and have encountered the same issue, which makes me think that maybe it's something to do with my setup.
Solved by installing Python version 3.1.0, in which the Python runtime and the IDLE editor both seem to work with no problems (so far).
I would add that:
