Also, have you tried doing the gmail IMAP setup trick? When it asks you your email address, type in .con instead of .com, and uncheck "Automatically detect settings". You should now be able to manually enter in the settings for your Yahoo account instead of having Windows automatically configure it for IMAP. (you have to do it that way for Gmail if you want IMAP instead of POP3). After you have the email account setup, you can go back into it and change the .con to .com while not losing your specific settings.
