So sorry, I was in the wrong place. Anyway, I have to give you a little background before I explain what I've seen in the right place.
I had to have my hard drive replaced in 2/08. In the process of moving my home folder back onto the system after a new install, (SuperDuper backup), I apparently misunderstood the directions, ending up with administrator folders that I had no privileges to access. I had to find the actual thread I posted on, to remember what I did to fix this, & here that is:
"I guess if I had been a little more patient, I could have figured this out. I was absolutely not happy about facing another erase/install in 3 days especially after the HD crash & burn on Saturday night. Out of desperation, I simply went in & deleted all admin accounts but the one that MA migrated over to the new drive on Saturday & SUCCESS! I have made a couple of trial downloads of several things with no errors, bought one album from Amazon which is download right now, so it looks like I'm good to go, no erase/install required."
I still periodically find these files/folders that have the red "-" through them that I can't access. Once I was in the right place, the location you were giving me was such a folder. In fact, it was the whole library folder. I sent that folder to trash, did a restart, & I'm not sure what I'm looking for, now, but the font book still opened on the restart. It's always opened on a restart, etc.
I do appreciate you trying to sort this out for me.
