When i move my cursor to the top left corner of the screen, I am automatically logged off. Is it a software problem or is it a feature I can turn off?

I have the problem too. Although for me, the top left corner was set in hot corners to activate the screensaver. I've set it to nothing, and will see if the problem persists.

I don't think there is an option for logging off in the Hot Corners, but check Mission Control System Prefs, Hot Corners button. What is set in the top, left.

I have the same problem. Very annoying. Did you solve the problem?

I'm having the same problem and it's driving me crazy. I checked on the hot corners configuration and there is nothing set for that corner. So it's something else. Either it is sending a logout command or it's crashing the UX.

You might want to consider starting a new discussion. Since this one is a couple of years old, less people are likely to look at it. A new post would be much more visible. You can link to this one.
