Invalid access to memory

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)> Actually, the problem is not rare, it tries to keep me logged in, I don't want that.
<If relevant, consider attaching a session log file or a screenshot)>
