Bill,

>It's used by all the classes in _base.vcx.

Frankly, once I opened the first few classes in the FFC and looked at the code, I decided to avoid the FFC, because it does a lot of heavyweight, performance robbing, stuff that IMHO is pretty worthless. If they have some class stuff that I actually want to use, I "borrow" the useful code that I want into a class hierarchy of my own design.
