Hi James,
Thought I would let you know, I didn't have to put the subclass in a separate Library. I now have 2 container classes in my base library "cnt" and "cnt3". The 3 reminds me to use it whenever I nest containers 3 levels deep. "cnt3" is just a sub-class of "cnt" with no changes. And my app works fine.

>Glad it worked for you.
