[gtkmm] Strange behaviour of my Gtk::Notebook.

["Andreas B. Thun" <abt gmx de>]

Hello,

I've created a Notebook with some
widgets arranged in a table on it.
On "button click" I create another
table and append it to the notebook
pages. New tab appears ....

.. when I click the append-Button size
of my current notebook window #1 doubles
in size!! Any hints for me?

TIA,
Andi
