Application Response

When applications are switched from, whether by the user directly switching to another application, or by a window spontaneously obscuring them (for example, incoming call), they receive a window deactivation event. Applications are written to respond accordingly. Static applications do nothing special in response. Dynamic applications such as media players and games will generally pause their activity, possibly expecting the user to manually unpause when they return. Applications are free to act as they choose, for example an audio playback might not pause at all, except when a call comes in.
