So this has been what has happened to me, way too much. Whenever I restart the computer....all my preferences are pretty much lost. But, not all. So, my desktop picture is what i had set it to, but my dock will be defaulted. I have to go to the pain of putting everything back in. Itunes? it pretends like ive opened it for the first time, but, my playlists will still be intact. IE and Safari run like i just ran them for the first time....Instant messanger keeps my buddies and such, but fonts, actions, profile, all that reverts back to old setting. Then stuff will start going screwy, iphoto screws up...Itunes quits with these "fatal error in saving music library" or something...my idisk wont open, ill restart...BAM, back to the whole default preferences thing. What should I do?
