Hi, I've been writing products for months... I really thought I knew how this stuff works. I'm running Zope 2.1.3 in debug mode. I make changes to a source file in a product, restart Zope, and the change is ignored. I stop Zope, delete all .pyc files in the product, start Zope - still nothing. I rename the source file, start Zope - sure enough, it complains that it can't find the file. Rename the file back, start Zope - it's still complaining about not finding the file.
