Did you tell it to remember your passwords and login and auto fill on? I have to hit the accept or login button if it's been past a certain time, but my info is already typed in.
If you're isn't, make sure your auto fill and saving passwords is turned on in your Internet Explorer settings. Then clear your internet cache and history. That will reforce it to ask you the question do you want to save the password and login for this website. Hit yes.
