My application tray broke after a recent windows update. I may be using the wrong name. I am referring to the application icons that appear by default at the bottom of the screen. Now when I have more than 1 window open for an app and I click in the application icon, the open windows blink on and then disappear. Before the update, when I clicked on an application icon, a small display representing each open window would appear and allow me to select from all of the open windows associated with the application. I am sometimes able to keep the display for each open window visible. Unfortunately, if I select in the display for an open window, the window comes up, behind its small representation and then the real window goes away when my mouse leaves the small window representation. I also just noticed that Alt Tab is broken and does not cycle through my open windows, but Windows Tab does still work.
