I do not know how to found this, becuase when I go to http://www.wolfram.com/products/mathematica/index.html and from there, I do not see a link to this "latest version" page, and that where I was stuck. But thanks for the link, good to know there is a page there with this info, even though it seems unlinked from the main product page. --Nasser > > ---- "Nasser M.
