Thank you all for your suggestions!
Turncoat's idea sounded to scary. I'm not sure that I wanted to delete ALL of my preferences (and I wasn't sure if I could do it from my own account or if I had to create a new admin account) but I appreciate the suggestion.
I tried Niel's suggestion, too, but it just said "folder cannot be found" or "folder does not exist".
Scott wins!
I actually had a Unix-savvy friend use the "chown" command on some of my file folders but he couldn't find the Trash folder. I only know enough Unix to not be afraid (but probably dangerous). Thank you, Scott. It worked
