The signin page keeps coming back when I or my wife try to sign on to our Yahoo Mail accounts. We are able to sign on to our Yahoo Messenger accounts.

Anyone else having problems with Yahoo Mail?

check your setting in internet operations you may have the box check
look under security were it says empty temp. int. files folders when browser is closed
if the box is checked uncheck it

Did a system restore and went back a couple of days. Now everything is working fine. Thanks for the clue.
