Hello Peter,
In general, run Repair Permissions after installing or upgrading
software.
To be accurate, it doesn’t actually repair permissions. Rather, it
simply resets permissions.
Permissions stay the way they are set until someone or something comes
along and sets them another way.
Extract from 'Take Control of Maintaining your Mac':
In Mac OS X, each file contains information specifying which users(or
parts of the system) can read it, modify it, or execute it.
This information is collectively known as permissions. If a file has
incorrect permissions, it can cause applications to misbehave in
various ways,such as crashing or failing to launch.
Ordinarily, installers set the correct permissions for the files they
install, and the permissions stay that way permanently.
However, a poorly written installer can mess up permissions—even for
files it did not install—and if you use Unix commands such as chown
and chmod,
you can accidentally set files’ permissions incorrectly. These sorts
of problems occur infrequently, but they do occur.
The Repair Permissions feature looks for certain software installed
using Apple’s installer, which leaves behind files called receipts
that list the locations and initial permissions of all the files in a
given package. Repair Permissions compares the current permissions to
those listed in the receipts and, if it finds any differences, changes
the files back.
The command ignores software installed in other ways (using a
different installer or drag-and-drop installation, for instance) and
knows nothing about legitimate permission changes you may have made
deliberately.
Cheers,
Ronni
Cheers Ronnie, Thanks for that ... I will make sure that I do that
after this next update.
Have I got this right,
Go to utilities, select Macintosh HD, click " Repair Dick Permissions"

Peter
