att/yahoo email and idsafe

monday att/yahoo upgraded their email service. no problems until today. when i log in, idsafe works like it should but now att/yahoo pops up asking me to enter my password.  this is not a norton problem but att/yahoos. i've rebooted hoping it would correct itself.  no go.  i'm posting here to see if any other norton-att/yahoo users are having this problem. thanks
