Started noticing this since the last patch. If the launcher is open while the game is running (as it usually is), it will accept gamepad inputs once the gamepad is active in the main application. In doing so, the player might inadvertently change settings in the launcher or use other features not intended from the launcher. Most common impact though is that the player inadvertently selects a news article or link and opens up a browser window, which pulls them out of the game. If the browser manages to open without pulling the player out, windows will continue to accumulate open until the PC becomes unstable. (100's of browser windows of the same ESO news or forums topic).
