Re: VPF data

All,

Found the problem......and a silly one it was. In the FAQs that describe how to
implement VPF, the properties term -.vpfPath is incorrectly written -.vpfpath.
I took the bad one, scratched my head a while, and finally decided to backtrack
in the source code. Found the correct term to be vpfPath and it works great.
Thanks, all!
