I have used Yahoo as my home page for over a year now with no problems, in the last three weeks every time I come to the welcome page and am asked to sign in I enter my name and password (very carefully!) but am always re-directed to the page which says 'invalid password' . I re-enter the information and am then able to sign into the home page...this happens every time without fail. I have mailed Yahoo but just keep getting auto-responses. Anyone got any ideas please?
