Thanks Basj, a reality check is always good. This will probably confuse the issue, but when I uninstalled Start11 before doing this most recent Start11 update, I went ahead and installed Start10 again to check it. WinFX did animate Start10. Uninstalled Start10, installed the most recent Start11, and it was back to ignoring it. You might check if you see that as well.
Thanks, at least now I can stop pondering assorted settings.
