its not a fault, just the design. the audya has to remember locations rather than file names. Its the same as when we loaded the 2011 upgrade - any registrations that pointed to a style has to be modified to take into account the new location.
once you realise that is how the audya operates its ok, but does mean we have to be more organized when handling programs and registrations (ensuring the correct order of autoloading .ins samples for instance)
