This is a bit strange, my Wifes Inc has 4.06.605.3 CL140944 release-keys with Kernel version 2.6.35-g55a06e5, yet it keeps announcing that it will reboot to install a new update. It goes through the countdown then does not reboot. Just goes back to normal as if there never was an update to install. Not being up on the latest Inc info, since I upgraded to the Thunderbolt, I THINK that she already has the latest update installed. Any ideas?
