Same here, across multiple browsers/computers. I can log in on the home page, then, when it finishes the "return to the previous page after login", it still doesn't show me as logged in. I have to click on the link that says "click here if your browser times out and doesn't return you to previous page" or something similar, before the timeout completes, and then I will stay logged in.
It's the ghost of Franko. Hi Franko.
