I have used Terry's code to write a script to find all of the the .pyc 
files on my system that were compiled with the 2.3 version of the 
compiler, and I have removed these files.

But my underlying problem still occurs: somewhere somebody is calling 
for the 2.3 version of the Python vm .dll and not finding it.  This is 
happening under Pydev/Eclipse and my only recourse is to blow Eclipse 
away using Task Manager.

So maybe I have  a .pyd file somewhere that is a 2.3 extension.

Is there a way to examine .pyd files to see if they were built for 
Python 2.3?

Finally, are there any other possible file extension types that I should 
be looking at?

Thanks,

Don.
