before you sign in (click cancel when it tries to) then there is 4 'objects'
"Type your email address here"
"remember me"
"remember my password"
"sign me in automatically"
(or words to that effect)
just un tick the "sign me in automatically" option and then (hopefully) it should work for you
hope this helps!
