Hi Rich,
Appreciate your response and I am (as I type) in the process of making a password recovery disk already. I also already have a second profile with Administrator privileges.
I may very well end up following your recommendation to delete the problematic account, however, am resisting that at present, as I will lose many settings, etc, that are not established or accessible under the second Administrator account. Any solutions that don't involve completely abandoning the present problematic Administrator account?
