Whenever I have more than one window open the active window seems to change unexpectedly without me even clicking in the window to activate it. For example I'll have one half of my screen streaming a Netflix video and the other half will be another window at some random website. I'll be typing something into the random website and all of a sudden the active window changes to the Netflix window and will affect the stream (pause/back/whatever depending on what I was typing in the other window). How can I stop the active window from changing unexpectedly?
