I don't know whether it was upgrading to the current TechTools and running diagnostics, repairing Permissions again, or if my e-mail program was waiting for the LiveJournal Permanent Account Sale, but Eudora is back to normal. Possibly a little better. Thanks for all the suggestions. I may, indeed, go to Thunderbird or something that will import Eudora mailboxes. For now, I'm good.
