Pentium 4 with XP Pro and office XP. When I run Yahoo.com mail, I have to log in twice. First time as I normally would and then hit log in under a different user and log in as I normally would again. It's like I have to fool the computer into thinking someone else has logged in. Once I open Yahoo mail I cannot click on any attachments or additional pages in an email. Can view the original email but if there is a web page or additional page address attached, I cannot access. Also cannot use address book. I can see it but it will not allow me to send mail from it. Any suggestions?
