IDLE and Pythonwin Keep Crashing

I ran into a similar problem trying to run a PyOpenGL program from within
pythonwin, so I wrote this script which can be run from the Pythonwin tools
menu to execute programs in an external process.

Put the attached script in site-packages\Pythonwin\pywin\framework and add
these commands to your Pythonwin options->tools menu:
    Run Externally:                        from pywin.framework import
runextern; runextern.run_c ()
    Run Externally (no console):    from pywin.framework import runextern;
runextern.run_w ()
    Debug in IDLE:                       from pywin.framework import
runextern; runextern.debug ()
