I have saved a hack for this:

I had the same issue with my IIS system, and had to use a workaround that
disables the KeyboardInterru pt from being processed. The code I use is
shown below.

see http://mail.python.org/pipermail/pyt...il/039881.html and
http://mail.python.org/pipermail/pyt...il/099002.html for an
explanation

These first two script blocks are needed because IIS looks for a SCRIPT

JScript or VBScript, but it won't be Python.

This is only a problem for this global.asa file.

<SCRIPT LANGUAGE=Jscrip t RUNAT=Server>

Note that recent win32alls also have this hack in place.
