Thank you all for the helpful input on the OSX 10.3.9/Acrobat 8 dilemma.
I haven't yet reinstalled the CS2 because I realized I want to upgrade first (although I realized that's not usually necessary) and here's why:
My hard drive was formatted by a friend who said it probably wouldn't be...
I have a 450MHz APG/Sawtooth single processor with 1.75 GB of memory (three 512MB cards are new.)
Two-month-old hard drive - Maxtor STM320080A
OS X on the 1st partition (98.18 GB)
OS 9 on the 2nd partition (29.92 GB.)
I have few peripherals at the moment; Sony monitor, Belkin USB hub...
