I must report this!
Today, after several weeks and just for the sake of it, I decided to try once more the whole routine of logging out, moving to a non Adobe site, deleting cookies, restarting, re-logging in, and trying to change my Adobe ID to my email address. Well, this time there were two noticeable differences:
1. Changing my Adobe ID to my email address did work,
and, most important:
2. I have stayed logged in after two browser restarts in Safari/Vista!!!
I am not aware of having done anything differently, so I think something must have changed in the site/software.
I am touching any wood in sight. And I guess that now I will only experience the "normal" logouts other users have been reporting...
