well if u tap the back button when in a program it closes it. however if u hit the start button to go back to the start screen it will only hibernate it in memory. in that case ud simply hit the back button to resume to the app and depending on how the dev has the restore points in the app u can resume back to the point u left off otherwise u start from the beginning. wp7 Nodo only suspends one app in memory while mango supports 5 or more apps sustained in memory and a press and hold of the back button will bring them all up similar to a task manager and to close them u goto each and hit the back button till they exit. aunque the apps are sustained in memory they are actually not running or consuming any RAM or battery so no need to keep going to the task manager to keep apps under control like in WM or Android. hope that was clear enough for u
