Thanks, Michael - no I just gave an example of a 1 second file to prove
the point that a long file was not a necessary condition for the problem.   
I simply can't import any WAV file when Prefs. are set to read directly
and Pitch (EAC) is default, and another user can't import MP3s with
Pitch (EAC) on.
