Oops, the focus manager didn't consumed mouse events. Therefore they were 
propagated to the parent (which was focused then).
Fixed in CVS.

Argl, every change to the source does produce bugs.
There was missing an break; statement.
Should be fixed in CVS.

If a focused widget is going to be hidden or removed,
the root pane will be focused.
Try to add your keyboard handlers to the root pane.
There is also support for event listener and event grabber
(using some of UContext's methods) but I consider it somehow broken ..
