Hi!

I guess I figured out..
All radio buttons that automatically interact between them must be on the same group, and from what I see 
it's not what you did.. look:

                ^---- here
you get it's group.... and....?
you have to make a single GSList *, for all radio buttons that will be on the
same group, and as you create new buttons, you append them to the list,
like this:

     radio = gtk_radio_button_new(group);
     group = g_slist_append (group, radio);
     gtk_radio_button_set_group (GTK_RADIO_BUTTON (radio), group);  

You don't need to update the already defined radios 'cose you're working with
the GSList, if you append an element the list header doesn't change, but
this list gets "automaticaly updated" 'cose the main node is the same for all..
Hope you undestand this.. hehe
