"Select windows when mouse moves over" doesn't move keyboard

I’m running SuSE 11.0 on a Dell Latitude D800.

In Control Center/Look and Feel/Windows/Window Preferences, I selected “Select windows when the mouse moves over them” (but not “Raise selected windows after an interval”.
In 10.x this would cause the keyboard focus and the mouse focus to move to the new window. In 11.0, the mouse focus moves to the new window, allowing me to scroll with the mouse wheel, but keyboard focus doesn’t move to the new window.
Is this broken, or (more likely) did I not set something properly?
