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)enter image description here

My colleague sees the same behavior returning from sleep on his MB Air. It's not intermittent behaviour though. Happens always when returning from sleep. – Ian C. Jun 24 '12 at 13:12
@IanC. the solution suggested bellow seems to work. – latusaki Jun 25 '12 at 20:50

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 & Privacy.

It looks like the issue is fixed. Although I think apple should do something about this. Thanks! – latusaki Jun 25 '12 at 20:49

Before I saw this answer, I turned off automatic logout and haven't seen the problem since.
