It's because it's more complex than that, as soon as you use controls 
made in Gambas that actually are containers. There is the notion of 
"proxy" controls that are the real controls that get the focus in place 
of the control you call SetFocus() on.

I will write GUI methods "FocusNext" / "FocusPrevious" (or something 
like that) that handle all the stuff and the corner cases.
