Richard, Thanks for the hint. Yes, you are right, as expected the results are the same as in the real 8.2 when I use -version-. My only problem now is that I have to figure out what exactly the difference between the two version is and which one I should trust (and how to justify that). The whatsnew just tells me that rotate has been expanded with new methods of rotations, but I don't see how that should affect my usage of VARIMAX. I guess something has been changed on how that rotation works, perhaps a starting value? Any clues?
