Strange problem this one!I have recently updated my drivers and installed BF3 - i have no idea if this is the cause, but recently i have been experiencing:a. When browsing, if i have a few windows open, i may be reading one page, when without me touching anything it will flip to another window.b. When in Steam, be it a game or just browsing through the Steam pages, it will switch to desktop - not crash as the game will still be running, just switch to desktop - v annoying.Any ideas what i have done?!
