BusyReset resets the counter that specifies how much time has elapsed between accesses to the user's input events. If the busy cursor is currently being displayed, this routine restores the original cursor.
The delayTicks parameter is the new value of the busy-cursor delay, expressed in ticks.
MacApp calls BusyReset from several global routines that implement the busy-cursor mechanism. You can call this routine when you wish to restore the cursor information record to a known state.
