I agree. That's the behaviour that I programmed for the listbox in the Address Book for Microsoft's email product, which you should see in MS Outlook (they might have changed the behaviour since then). The main difference for that address listbox versus most listboxes/listviews is that the address listbox will update the display to show the sublist of matching items (and do the hard work of updating the scrollbar to show the size of this sublist and how many items are in view). The expectation was the user would move the cursor with arrow keys or type more or the desired substring if the cursor wasn't placed on the desired item.
