Hy Janusz,

Thank you, but I only doed yet one own full GTK based application (Orca 
Teacher), and I always learning, because very interesting the GTK 
programming.
I am affected too with A11y related, because I using too Ubuntu releases 
with Orca screen reader. If we future more this type problems trying 
fixing and try helping easyest A11y developers work this easy fixes, any 
Ubuntu or GNOME releases is will be better and better for A11y related.
