When I first installled Tiger I was checking out how to set up different accounts for different users. I really had no need for this so we just use one account. Never had a problem til yesterday. I was messing around in the Core Services in the system folder. I double clicked on MirrorAgent but nothing seemed to happen. My computer was running slowly so I began closing un-needed apps. When I got to the mail it froze up. I tried to restart but got the message that "MirrorAgent" would not allow a restart. It instructed me to quit it but I saw nothing that even said it was running. I did a hard shut down. When I logged back in on MY ACCOUNT all my settings were gone. There was a generic dock. No desktop pic, no bookmarks, nothing. When I double click my mail it prompts me to set it up. I am afraid that if I do this it will delete all the folders (extremely organized) that I had set up. Has ANYONE ever heard of this. PLEASE PLEASE PLEASE HELP!
