Please restate your question.  I don't think it makes sense for CFatRat to 
evaluate to False for a negative number. -- Darren Duncan

Thanks, Darren -

It doesn't make a lot of sense to me, either.  Maybe how I should have
asked: Why does FatRat evaluate to False when negative if it is a value of
a KeyWeight?  Does that make more sense?

Quite possibly I'm just reading S32/Containers wrongly.
