I have downloaded the pre-release version of Internet Explorer 10. When I sign in I check the box to keep me signed in. But it doe not. Almost every time I restart my computer, I have to sign in again at Internet Explorer sites, including Windows Live Mail. I have told being signed out is a security feature of IE 10. Is that correct? If so is there a workaround? If not, why am I signed out when I have indicated I want to remain signed in?
