Comment 1 for bug 260939

I've just found it's also possible for the "Window Selector" to give the wrong list of items.

If I select a program on the second monitor, then click on the Window Selector, it shows the contents of both screens. If however I then right-click on the Window Selector, then left-click on it again, it now shows only the contents of the first monitor (where the window selector panel is located).

So far alt-tab has proven reliable, but it's very disconcerting to be not quite sure of what programs are running.
