I get so many support requests of "I clicked on a link and then I was logged-out".
They weren't logged-out, they just didn't notice that the link was opened in the wrong browser. Doesn't help that most browsers kind of all look the same.
Honestly, for a non-techie I think the "I was logged out" is totally reasonable. I'd bet that a majority of Internet users aren't going to recognize that the UI has changed, especially when they're focused on getting some other task done.
