I'm running the latest version of Mountain Lion as of this post, and whenever I wake my 2009 17" MacBook Pro from sleep, Mountain Lion asks for my password. I type in my password, and the desktop appears as normal. However, within 10-30 seconds, it goes back to the same login screen I saw when I first woke my Mac, and it asks for my password again.
What is causing this, and how do I fix it?
