Whenever I press F3, my computer opens Chrome. I need F3 for some shortcuts. Why does F3 launch Chrome?
Do you have one of those annoying keyboards that combines the F-keys and the media keys together into one set of physical buttons? If so you switch between F-functions and Media functions by pressing the Fn button. I have known these keyboards to default to using the media keys setting and not the F-key setting at bootup.
