回复：哈哈，能还不教一下？！先谢一百下：）

Right click on the mighty mouse, select "empty trash"! Of course, you need to preset the right click in system preference prior to do that. Otherwise, press and hold "control" key then click "trash" icon, you should be able to see "empty trach" there.

右点鼠标在trash, 或者按着 "option" 键，点 trash,你都能看到。
