Put me in the "want to help, not bitch" camp. Here's some info: Chrome, latest versions. Ipad 4 or Windows 7.
Randomly logged off. Also: there are times I will start a session, not bother logging in - and software shows I am not logged in. Suddenly, while reading a thread, the software logs me in; sometimes the login carries complete functionality - all the account menu options work. Other times, the login appears "incomplete": I can read private messages, but I cannot get into my profile - software errors out with "You must be logged in to perform this function" although it shows my avatar, and really looks like I am logged in.
The random logoff thing still happens, even after a random login.
This started, I believe, on Monday.
Hope that helps.
