I have two sunbox both running os 8, both running Zope 2.3.3, both running python 2.0.1. The product imports several python modules which in turn are initialized as objects but only the top-level module is registered. When you install the product into a folder it initializes the other objects or products. One of the modules cannot be imported on machine 2 but has no problems on machine 1. If the module or class file being imported had syntax errors would the syntax errors show in the zope control_panel under the broken product or would it just simply show the error in the parent product and simply refuse to acknowledge the module giving an import error? I know this is ambiquous but any thoughts on where to start looking as to why it would install on one identical box, identical code and not on the next? Could it be ZODB and Refresh has mangled something? Scott Pierce Sonopress US - Digital Services 828.658.6157
