SetMultitaskingMode (int mode)

If MODE is 0 (the default), then if the user Alt+Tabs out of your game, or clicks on another window, the game will pause and not continue until they switch back into the game.

If MODE is 1, then the game will continue to run in the background if the user switches away (useful if, for example, you are just making some sort of jukebox music player with AGS).

Note that mode 1 does not work with some graphics cards in full-screen mode, so you should only rely on it working when your game is run in windowed mode.
