The issue is that sometimes, if you press ctrl-c on Windows, instead of raising a KeyboardInterrupt, Python will exit completely. Because of this, any program that relies on ctrl-c/KeyboardInterrupt is not guaranteed to work on windows. Also, working with the interactive interpreter becomes really annoying for those with the habit of deleting the whole input line via ctrl-c.

Idle Shell, 3.3.0a4, Win 7does not seem to have this problem. Still up after 6000 ^Cs. It is better anyway, in multiple ways, than Command Prompt. (That does not help batch-mode programs, though.)

That aside, perhaps the way it handles ^C might help.

I did get the CP to close four times, each time after a few hundred to maybe a thousand ^Cs. It seems to require more than just one held down key press. I suspect the closures happened after the limited line buffer was filled and it was starting to delete the earliest lines.
