I am running os x 10.4.8 and I have system preferences 3.5, I am having problems. I was playing around with the screensaver menu and i set the itunes artwork to display 2 rows. I hit okay and i got an error. I thought, "Okay well i can just put it back and everything will be okay." But it turns out it won't let me put it back to what it was previously, i come to the use new settings or original settings box and regardless of what i click it doesn't change. I have logged in and out, shut down and booted back up. Please help. I am beginning to lose faith in macs, i am coming from windows and i thought they were supposed to be better. My macbook is living up to its beauty but not the brains.
