Sub-Assemblies and Photoworks

Greetings,
This is my first post, so please be patient as I may not havedeveloped the savvy descriptive ways most users on here do, but Iwill do my best to describe my problem.
Has anyone ever had this problem with Photoworks? I have parts thathave materials applied in Photoworks, which are used in various subassemblies, which when placed in top-level assemblies and rendered,their materials do not render in the image, and appear to beover-ridden with the default material.
The only fix I have come across is to open the sub-assembly, andthen the part(s) within it, then go back to the top-level assemblywhich subsequently will render properly.
All parts and materials reside locally, not over a network. Theonly portion of the file that does reside over a network would bethe part and assembly templates.

Any tips, suggestions or guidance will be very much appreciated.

Thanks,
Kyle
