Ouch.  That's not the problem.  This is fallout from making DataSkins more
"personally responsible"; the bug is in the propertysheet providers that
expect to acquire from a parent.  They need to be rewritten to work the way
dataskins do now, or else configured to find the parent providers, and
provide those instead.  :(  I'll have to take a closer look at this later.

By the way, I've been away from the list a while due to day-to-day business
concerns and travel.  I'm hoping to start the process of catching up soon,
but I saw this and since it's a bug I'm going to tackle it first before
trying to answer any other unanswered questions that might be floating
around out there.  Sorry.
