Jay,

I am afraid Bob is right about reinstall of Panther to get Apple's  
version of Python working. I remember looking through the install CD's  
to see if I could find the python package but I think it is in the BSD  
subsystem and cannot be installed separately ? I did the same thing as  
you and originally tried to rely on the Fink version (for ZEM), but it  
did not work and I had to reinstall Apple's python.

I ran into this problem trying to get ZopeEditManager working (a python  
- pyobjc app). Zachery Bir, the developer of that package told me that  
it probably would not work without Apple's version of python. It seems  
a little brittle to me because I thought one could download the newest  
version of Python, add the necessary modules and have a working system,  
but apparently the windowing system for a python/Aqua app relies on  
Apple's framework version of python. It was true for the pyobjc app and  
now seems to be true for a PyQt app. The symptom you mentioned sounds  
the same. That of double clicking the app and seeing the icon zoom out  
like it is going to open and then nothing happens. Nothing shows up in  
the dock.

It is a big pain to reinstall and then do all of the updates, but it  
might be worth a try. Eric WILL work for you eventually but I think you  
are going to have to use Apple's python.

Good luck (and happy holiday everyone),

Brian

P.S. Kevin - I noticed that my emails to the list are not showing up in  
the threads in the Mail app. Do I need to CC myself or something to  
keep the threads in order ?

Thanks
