Lion Logging out randomly (MacBook Air)

Question

Lion Logging out randomly (MacBook Air)

Every once in a while my Macbook Air will log me out as if I had specified it to do so.

What's peculiar is it only happens when i'm running java-based applications. A game for example that uses JavaScript - I could be 15 minutes into the game then everything freezes and within seconds I'm at the login screen. When I log back in, the apps that I was running open up again like is if all was normal.

This has happened at least 7 times already. Not sure if this is a graphic card, logic board issue or what. If anyone has experienced the same problem or knows what this might be, please feel free to share.

Specs

Macbook Air (late 2010)

2 GB 1067 MHz DDr3

1.86 GHz Intel Core 2 Duo

Any additional details needed, please let me know.

MacBook Air, Mac OS X (10.7)

Same problem here, I have been lucky that my mystery logouts get stopped by dialog boxes asking if I really want to quit.

Edit: Should note under System Preferences -> Security & Privacy -> Log out after X minutes of inactivity is not selected.

Same thing just happened to me. Lion simply logged me out all of a sudden. I was writing code in Eclipse, which is a major Java app. Also, I connected a bluetooth Apple keyboard to my macbook Air...

Weird stuff....

I should've responded a long time ago since I found a solution some time ago.

What I did to fix the issue was to go to System Preferences > Energy Saver and put Computer and Display Sleep to Never. Keep it like that and the problem should disappear. After a week or so like that, I switched it back to defaults and it worked fine - haven't had a problem since.

You may have to keep it on "never" though and just put your computer to sleep manually.
