Compose in 11.1/KDE4/YaST?

Hi all,

I am trying to understand how to enable keyboard composing?

When I run:
YaST | System | Hardware | Keyboard Layout | Options
(I think it is managing SaX2-X11 settings?), I have selected a compose key position. And if I test it (by typing in a Konsole) - it works!!

However, log out and back in and it has stopped working. So I drill back down the above path, testing at each step and the moment I highlight the (already selected) Compose Key Position, it starts working.

What is happening in this GUI at this point? Why is it not being honoured during a log off/on sequence?

Regards, Martin
