it is perherps the better solution, pubished by Theodore Gray
in The Mathematica Jounal 7(3).

It write to the status line of the notebook, don't fill you
notbook with print messages and I think it is the right place
to have a progress report with

ShowStatus[status_] :=


 FixedPoint[ (counter++;ShowStatus[counter];f[#]) & , x]

Hope that helps
