I use remember me in the login box so I (almost) never have to log in. For the past several weeks (probably since the update), if I am in the forum and click the Home button, I am no longer logged in. If I launch the site again from my shortcut, I'm back in again. Windows 7 Pro using Opera. Nothing earth shattering, but it just seems odd.
So, folks, give it about 20 min and post here if you see any problems. I might have to update a couple links or something.
