Yes, there was a problem with the Distances module. Please download
the new version (11 Sep 97).

In Clusters->Compute Distances (with Euclidean distance) the distance
is re-scaled bteween 0 and 1 (this is needed for the clustering algorithms).
In the Distances->Canonical Distances the distance is the raw Euclidean
distance. The Distances->ToClusters option allow you to rescale the
distances between 0 and 1.

>3- Is the option 'Distances|Principal Coordinates' size limited ?

Yes, but the size is limited only by the memory available in your computer.

>4- Is it the only way to perform a Multidimensional Scaling with ADE-4 ?

As far as I know, yes it is.

The documentation is now available (although it is the Macintosh version).

Well, most people seem to be able to now... What happens exactly ?
