It's really easy to see if you trace out, in detail, the exact order in which things happen and when each object is initialized and shows up in the respective module's namespace. The general rule is: don't do that. It doesn't work, and the hoops you have to go through to force it to work are so complex and bizzare that they're not worth it. Redesign the modules so you don't have cyclic dependencies. John Roth -- http://mail.python.org/mailman/listinfo/python-list
