Hi David

>this had no effect whatsoever, pressing ok didn't cause anything to happen.

You have to fill the boxes entirely. Especially The D inner product
(default=1/n) box.
As written in the module documentation of MatAlg cliking the corresponding
finger will display a window for the definition of matrix D. In the example
"ChatBis" you have to select "2" since matrix D is in file xx.cmpl.

In my answer I just wanted to show what the CategCovar meant theoretically.
For simple use you do not need it since the listing of the MCA module
incorporates all the material for interpreting the data (including
correlation ratios).

OK. that is true the filename is now Mafragh_MilQ (97-11) instead of Mil. I
got the same results than those of the documentation using this file. The
Mafragh_Cla (97-1) file is not useful here.

Best wishes. Hope Jean can answer to your multiple crashes.
