How can I open my Yahoo mailbox when using IE8 - keeps repeatedly asking for my password.?

When using IE8, I can sign into Yahoo, but cannot open my mailbox - keeps repeatedly asking for password. I can open my mailbox when I use other browsers. Does anyone have a solution to this problem?|||Make sure you click Keep me signed in for 2 weeks. Also it's caused by the Yahoo cookies being deleted when you close the browser. If you are using IE then go to and click Tools, click Internet options. Go to privacy and make sure the level is medium. For Firefox click Tools, then options, at privacy check the cookies options. Some anti virus/spyware may be deleting the cookies
