bug with wclear ano/or werase?

[Christ, Bryan]

Does anyone know if this is a bug...

I have a subwin which is a subwin of a subwin (say that 3 times fast).
In pictorial representation it would be:

real_window (size 20x30)
     |-----subwin_a (size 15x25)
              |------subwin_b (size 10x20)

When I do a wbkgdset on subwin_b then follow it with a wclear or werase,
the subwin_a actually gets affected.  However, when I do a box() on
subwin_b, all works fine.

Anyone?

Thanks in advance,
Bryan Christ
