We fire state change events when a the focus changes. Unfortunately MSAA state change events don't come with event data to show what state changed. The screen readers look for state change for the STATE_BUSY state on a document to determine when a document is starting to load or is finished. As a result, even just going to the menubar and hitting Escape is causing Window-Eyes to reload the page. We should fix this by only firing the state change for focus events in ATK.
