OSX Lion freeze after sleep Sometimes, after I wake up my MBP from sleep I get the screen shown in picture. Once I click somewhere in the middle of the screen I get the log in window. When I log in all the windows/apps that were open before sleep are closed. This doesn't happen always but it happens quite often. Any suggestions? Has anyone had same problem ? This started happening after installing SSD. (Crucial M4)
I've experienced this as well. The error is actually related to the settings of diplay sleep and computer sleep:


  In System Preferences > Energy Saver the timers for display sleep and computer sleep must be greater than the time of auto logout after inactivity in System Preferences > Security &amp; Privacy.
