Hi to all, I had to reinstall osx on my intel mac and was not sure if CS3 would work. I updated to 10.6.8.
I can report that CS3 it is working as normal for me.
I installed the old free version of linotype font explorer too. It is working but seems to suffer some slowdown on startup.
I only use quark 8, CS3, and fontexplorer.
Peace and and live long and prosper yadda yadda.
