There are user interface conventions/guidelines for mice with mouse
wheels (typically a wheel between the 2 mouse buttons you can spin
forward or backwards with a finger). If a scrollable user interface
object has the focus and you spin the wheel, the user interface object
(field, scrolling pane, slide, whatever) should "scroll" without you
having to point to it or click on it.

I am unfamiliar with the A1152 Apple mouse (although I just googled a
picture of it). I don't know is the "scroll ball" of that mouse is
supposed to act like a "scroll wheel". Here is a typical HP (windows)
2-button mouse with a scroll wheel for comparison:

I don't know if that information helps, but there it is.
