For Apple Macintosh users: If you use Qualcomm Eudora (or Eudora Lite) as your e-mail client to reply to messages, you need to take an extra step to make your reply work correctly. The Subject field of the message to which you are replying contains a string that includes an equal sign (=) followed by a number. Copy the contents of this string, starting at the equal sign and continuing to the end of the line. Then paste what you have copied into the Subject field of your reply message before you send it.
