There will be a full traceback on the console. This means
either the  
terminal it was started from, or console.log.

No that's not what it means. Chances are, you just aren't
looking for  
the print output in the right place.

Figure out where the stdout is going. I can't help you
without a  
reproducible example or at least a traceback to look at.
Also,  
versions are useful information too (OS, Python, py2app).

I figured out my problem. I was opening the Console
application, but 
somehow I had switched it to look at the wrong log file
without 
realizing it (it almost always opens automatically to
console.log, since 
that's the log file I'm almost always interested in).

As I expected, once I was able to look at the traceback it
was easy to 
fix the problem.

Thanks for the reply,

Mike
