You can switch between Horizon Client and other apps without losing a remote desktop or published application connection, and you can resize the Horizon Client app so that it takes up part of the screen alongside another app.

If you leave a session idle for some amount of time, you receive a prompt before the session times out, asking if you want to keep the session alive. To keep the session alive, tap or click anywhere on the screen, or press a key on your keyboard. If enough time has passed so that the connection to the remote desktop or published application is lost, Horizon Client returns to the desktop and application selection window and prompts you to reconnect.
