I just recently loaded this SW (mid-May?), and it has been happening pretty consistently when I leave the laptop running overnight. I thought initially that it might be due to the wireless LAN card powering down during "inactivity", but this morning I saw the crash while I was surfing the web and doing other work on the machine.

You can reach me at dmurphstein on gmail if you have questions or want more info.

It might have to do with a virus scanner. Another thread on the subject
