General Taskbar Flashing (PC Only) Added support for flashing the game on the taskbar if something important happens while DCUO is not your currently active window, including: Your On-Duty queue is ready. You receive a group or league invitation. You receive a tell. You receive a trade or duel request. You (or your pets) take damage. This feature is really good. While I was doing Wonderverse bounties another idea came up in my mind. What about flashing the game when the initial warning message pop up for Wonderverse and Legion open world bosses?
