On my system,
Fourier[{1,1,1,-1,-1,-1}] returns the same as on your system, however
Fourier[1.,1.,1.,-1.,-1.,-1.}] returns a numerical result. I guess I
had never tried to do fourier transforms on integers before. The funny
thing is that the example on page 111 of version 2 of the mathematic
book does give the impression that numerical results will be returned
for integer input to the function Fourier.
