The other items in the "Sliding focus" group can then be used to influence the behavior of this feature:
If this setting is disabled, &xwp; will only give the window under the mouse pointer the keyboard focus, without raising the window itself. As a result, the active window and the topmost window need not be the same. This allows you, for example, to type into a window in the background.
If this setting is checked, seamless &winos2; windows will never be given focus when the mouse is moved over them. This effectively restores the original &os2; behavior for seamless &winos2; windows. You thus have to click into them to have them activated.
If this setting is unchecked, &winos2; windows will always be brought to the foreground when the mouse is moved over them, no matter whether the "Bring windows to top" setting is checked.
