Twice now, a few weeks apart, I've gotten to the main LttD page, clicked the Login link, and found myself looking at my "Home", but with the wrong layout and I'm not actually logged in. The "Login" link in the top right corner does nothing.
Both times that this has happened, I've switched to Mozilla and everything works fine.
It is still doing the same thing. In IE, I click the Login link and it takes me to a different place than it does clicking the same link in Mozilla.
