Dear all, I've been trying to run some downloads overnight, but in the morning when I wake up the screen, I've been logged off my computer. It's happened a couple times now, so I'm pretty sure it's not a power supply issue. I've looked, but I can't find any settings about auto-log off in the Help files, or in the System Preferences. Any input? BTW, I've set up a guest account on my computer and I'm deleting that to see if it resolves the problem. If so, great, if not, your input is appreciated. Thanks.
