That worked once, when I clicked on the link you provided. Then I went to my homepage and typed in the yahoo address on the "address" bar. Went to yahoo, clicked on "mail", and entered my password. The screen displayed the yahoo headers, but was otherwise blank. In the lower left corner of the screen was the word "Done". I clicked on refresh, but the same thing happened.

Heeeeeeeeeeeeeeeeeeeeelp!
