Grey screen, then login.

[WillEH]

Hi, I could be just randomly typing something or doing anything, and then the screen goes gray and it kicks me back to the login screen. All my work is unsaved and lost?

Happened 2 times in the last 5 hours..

any idea?

2011 MBP, i7, 8GB, running Lion.

Thanks

This has happened to me before when I upgraded to Lion. Since then I have done a clean install and it hasn't happened since.

Any fix for this? Anyone with the same issue.. really getting annoying now. I did clean install of Lion few days ago.

This is crazy. I already thought it was mad that Lion would decide you were no longer using apps and close them - now it's deciding you want to log out?

I guess, "Lion knows best".

But seriously, that's an odd one, can't imagine what might cause such, sorry, I just couldn't resist.
