One problem occurs when users exchange a Business Card (or Personal Catalog) between a non AV Macintosh and an AV system. The Business Card (Personal Catalog) will be damaged when opened on the AV system. PowerTalk has a built-in repair function, but a user confirmation dialog will be brought up every time such repair takes place.
Before installing System 7 Pro on Quadra 840AV or Centris/Quadra 660AV, make sure you have System Enabler 088 1.0.1 or later installed.
Version 1.0.1 (or later) of System Enabler 088 is available from the Apple Software Updates Web site at http://www.apple.com/swupdates/ .
