As Dougsg38p says, keypad and trackwheel events are only delivered to the application with focus. The only exception is that in later OS versions they have started delivering some ancillary events (volume up/down, call star/end and the like) to background applications. If I remember correctly that started in OS 6, possibly OS 5.
My other Blackberry is a PlayBook.
