Hi Tom,
I am confident of each of my actions throughout this process, except
that I don't remember if I copied the iCal folder to my G4 iMac and then
tested it after I updated my father's Intel iMac to SL, as I did several
times prior to the SL update.

I tried this shortly after I posted my message this morning, and it
worked. First, I exported the calendar (xxx) that was on the Intel
iMac. Then, I copied it to my G4 iMac via MobileMe. Then, I deleted
the entire calendar of the same name and filename (xxx.ics) from my G4
iMac iCal. Then, I imported the calendar of this filename (from the
Intel iMac) to my G4 iMac iCal. It worked perfectly. There were no
duplicates.

Actually, I want to get to the point where I am updating my G4 iMac iCal
from the Intel iMac iCal via my MobileMe account until I can buy a new
iMac. With so much on my plate at this time, I'm not there yet. Thank
you for the suggestion.
