Widget focus

[Markus Uhle <markus uhle synergetik de>]

Hi!

I have a strange problem with the "moving" of the focus of the widgets
in a window (GTK1.2.10 - Embedded System):

Let there be 3 push-bottons in a window and the first one has the 
keyboard focus.
Now I press "cursor down" and the next button gets the keyboard focus.
Same procedure for the third button.

But when I press now "cursor down", the focus goes elsewhere, but not 
back to
the first button. This happens after another "cursor down".

It seems, that something like "the window" or "the container" gets the 
focus.
I tried to understand the sourcefiles gtk_window.c and gtk_container.c, but
I do not get any simple solution for this problem.

Maybe someone can help me....
Thanks,
Markus
