Mad Jew I have been looking on things and can give you, and the rest who has been looking on this tread.
I ran a Archive and Install and I sat up the User Accounts, and it worked -fast switching on 4 different account and 3 languages.
I went back to the main account and I got an "Error 10 from Norton Antivirus" with a request of re-installing the virus protection. I did that, but not before I had all the various OSX updates installed to secure everything was still working.
I then re-installed Norton Antivirus and guess what... Back to where I started, meaning only 1 account could be accessed. Just lovely, 2 hours just wasted.
I ran Archive and Install one more time, and everything worked again perfectly.
Now, if you hear about a sales dude in a Hong Kong Apple Store, who sold me Norton Antivirus and said it was perfect, who have his mouth shaped as a Norton Antivirus box. Then it was me who did it. -No I did not get my money back, as service has yet to arrive in Hong Kong, but no more buying Apple gear in Hong Kong. I suspect the software I bought was a copy/fake but in "original" packing.
Oh yes, the external microphone is working again.
Mad Jew I really appreciate your help on this problem.
Thanks
Mr. Crowley
