Hi Ronni,
        Thanks for the info and don’t fret about not replying earlier,  it has 
been a very busy time for all.  Actually, my Wife and I took off for a week at 
Jurien just after I posted my last request so couldn’t do much about the 
problem anyway.

Thing are now, thanks to your assistance, going fine.  It just took the old 
computer about two and a half hours to download, install and update the system 
and Safari is now back in business.

Thanks again and all the very best for the year and beyond.

Regards

John
