Certainly your suggestion will allow me to overcome the problem but it 
doesn't explain why, when 'wwGlobalDB' and 'wwLocalDB' are removed and 
the code runs, that it works. Only when I don't delete it does it fail. 
This is pretty strange.

Suppose I have

aa.py

a = None
def foo(b):
	global a
	a = b

b.py

from aa import a

def bar():
	print a

c.py

import aa
import b
a.foo(23)
b.bar()


Why is this code incorrect? Wouldn't I see 23 printed?
