Unity still receives OnMouseOver events while in background

As the title says…
My game is a multiplayer game over network and I don’t want it to pause whenever the game looses focus (via ALT+TAB or whatever). Therefore I set the runInBackground flag to true. However I noticed that when the window of the game is behing let’s say Google Chrome for instance, I still hear the game reacting to the mouseover events (because my buttons trigger a sound when they are hovered). Is it normal? What am I missing here?

Thanks!

You should be able to use OnApplicationFocus to detect when your game is in the background and then ignore input when your app isn’t focused.
