My powerbook... my powerbook... my poor poor powerbook. All of a sudden, I'm having major access problems on MY OWN powerbook. I can't modify the desktop AT ALL because "I don't have significant access privileges." I'm the only one who uses it! I've gone into the system preferences and tried to figure out the problem (and I'm moderately computer savvy) but to no avail. For other programs, I have to enter passwords for a bunch of functions that I've never had to enter passwords for before. I can't imagine what I've done to cause this problem. Any ideas on how to fix it?
