This is one reason why I prefer keyboard-based UIs that do not automatically change anything that affects the UI while the UI is active (and being able to select things by entering a number or a name also helps, rather than having to use the arrows). (I also dislike touch-screen for many other reasons.)

haha ... looks like "follow the money" applies yet again to get to the root cause ...
