HMMM be very careful doing what I suggested above, when I changed the user back to "normal", "my pc" lost all its icons and there were some other issues.
Some corruption occurred during the process, the log file had hundreds of "duplicate ownership" messages.
Took two hours to sort it out.
Fresh extensive system build everything straight forward except NIStune, 4 hours plus trying to do a simple install on a "standard" user account !!!
NOT HAPPY ! LOOK AT THE F$%kIN TIME !
