Disk Permissions

[Dave Morrison]

I'm slowly coming to terms with my new PowerBook, but this thing called
"Disk Permissions" has me baffled. What are they? Why do they keep getting
changed or broken? Why, after doing the "Repair Disk Permissions" in my Disk
Utility and "locking" it to "prevent further changes" do I find the
permissions changed again within a few days? Is this something I need to
worry about?

external burner and iDVD
