Just returned home from a trip during which my Intel iMac running 10.4.10 was left shut down. It was running fine before I left. Now, I am unable to log in to my primary admin account. I just get a generic desktop background after typing my password. No menus, Dock or anything else except the mouse pointer. I then tried logging into some other user accounts I have, and that worked briefly, but eventually things started freezing up in those accounts and I had to force a shut down. Booting in safe mode made no difference. I ran Disk Utility from my install disk and it found no problems. I also repaired perms while one of the other accounts was working, and I even used Diskwarrior to rebuild the directory. Finally, I tried moving the com.apple.loginwindow.plist file out of the Preferences for the account in question. Still no luck. Any ideas?
