it happens when i watch videos on anything which i'm running in fullscreen, including watching videos on websites like youtube. sadly i do not know what the process is called as the icon only appears in the taskbar very briefly, if there is a way to monitor the processes so i can find out what it is i would love to know excluding task manager as it only happens when i'm in full screen. it doesn't do much apart from take me out of fullscreen which isn't really a serious problem, its more of a annoyance. especially when flying heli's in dayz/arma and getting thrown out of fullscreen and to my desktop which usually end horribly for me, my team and the heli or when in a firefight in the fps games i play. also i forgot to mention that i have never had this problem before, i just randomly started out of nowhere and there isnt a set time at which it throws me out of fullscreen, it could be every few minutes or a few hours but until it happens i just play my games in fear knowing that at anytime i will be taken out of fullscreen. its kinda scary XD
