Return Eudora Pro 4.0 to the Old Look -- Marc Bizer <mlbizer@mail.utexas.edu> (and others) wrote to address Matt Neuburg's complaint in "The Postman Rings Again" in TidBITS-424. As with almost everything in the consummately flexible Eudora, you can revert to the old look that featured letters instead of icons in the status column of mailboxes. To do so, enter this one-line AppleScript into Script Editor and run it (you will be asked to find Eudora Pro). The script changes your Eudora Settings file; to reverse its action, rewrite the script to set setting 233 to "n" and run it again. [ACE]

tell application "Eudora" to set setting 233 to "y"
