It would be helpful if you told us how you normally receive and
send email. If that is via
http://mail.yahoo.com (using your browser),
take a look at this article:
http://help.yahoo.com/l/us/yahoo/mail/original/settings/settings-10.html
Steps 4 and 5 of that article need to be modified for Vista:
4. Click "Set programs".
5. Then click the first item: "Set your default programs."
After a few seconds, a list of programs comes up. Click on
Yahoo! Mail". Click "Set this program as default". Click OK.
Let us know if that works for you.
