For the last week I've had the following problem.

My email account works. I can sign out and back in. However I can't change any of the content on my main page nor can I
rearrange anything. It keeps on asking me to sign in with my password over and over again.

So far I've deleted all cookies reset safari and run diskwarrior 3.0. All to NO avail. I've even replied to yahoo's auto reply email per their instructions and have heard No response from them either.

What do I do now?
