Hi Jon, Thank you for trying to help me with this. The sharing and permissions do allow read & write etc. as below. I also downloaded Combo Updater as you suggested and it came back with this message;
Mac OS X update Combined can't be installed on this disk. This volume does not meet the requirements for this update.
I then checked Software Update and it came back as up to date.
Lastly, I went back to Time Machine and selected just Safari before the new download but it came back as can't be modified or deleted.
One final question, have you heard anything about the problems being fixed from upgrading from Lion to Mountain Lion? Alan
