I recently uninstalled Adobe CS2 on my new Macbook Pro running on 10.5.5 (have been receiving error since 10.5.3). I have been getting the intermittent error message upon startup "Where is System Events?" It then asks me to "Browse" for it. Is it a file that got deleted? How do I restore it? What is it? I do have Time Machine backups but don't know what I should be looking for.
