Hi! I was working up an answer to a post on MR relating to Fonts and Font Book, working through the details before I replied. I went into the Font Book app, not used for a few months, and ----- the "Resolve Duplicates" option was greyed out. Uh? This was on my desktop, a PM G4, so I went to my PB G4, both running Panther (fully updated), and it too had the Resolve Duplicates greyed out. And I KNOW that I did a succesful operation with it on the PB about 6 weeks ago. Any ideas/suggestions anybody? I've looked on so many Help sites before posting what might be a daft question here. Thanks for any help from anyone.
