This is off the present topic a bit, but I'm having what might be a
similar problem with some gtkmm code.  I'm trying to reparent some
control panels between a vbox in each of two windows.  When I do that,
some widgets get messed up and don't appear in the correct spot, instead
appearing in upper left corner.  Depending on the widget/panel, clicking
on it or focusing through it restores it to it's proper position, but
not always.

Could this behavior also be related to the focus lists?  Is there some
safe way to reparent to avoid the focus problem?
