Hi, John

Thanks for the .blend example, it helped : ).

I understand the problem now.  When you import a module in Python, it's
not part of the global dictionary (so doesn't get cleared with it). 
Only its contents are.

The module itself is put in this dict: sys.modules

So to solve the problem you report, do this at the end of the script
that imports the others (the one you run):
------------
#if you import a module that is a Blender Text, like:

import output

#end the script with this:

import sys
del (sys.modules['output'])

------------
same for each module you import this way, of course.

I tried to find a way to do this automatically, from C, but the code
would be awkward.  The Python way above is much, much cleaner.  We'll
add this info to a Blender Python FAQ, we'll need one.

Any problem, please tell us.  Thanks again : ).
