On AOS3 this doesn't work.
Of course it works. Just did that 3 days ago. But to be more precise Andy meant "the most recent version of AmigaOS Release 3" which translates to AmigaOS 3.9 (chances 3.5 would work as well are good). If your're still using an even more ancient version of AmigaOS, then it might not work (i.e. 3.1 or 3.0).
