Matt, I never check the box to stay logged in to IHUB but sometimes it keeps me logged in anyway.
This afternoon when I was going offline at lunch I clicked on "logout" even though I don't check the box but when I came back and went to IHUB it immediately brought me to my favorites without having to log in again.
I tried logging out again and it still kept me in.
I finally had to go to Tools, Internet options, delete files, and then I was logged out.
