This one is aside from the normal programming endeavors. Tommy’s laptop, Vista installed, is refusing to logoff the current user. It has been saying "Logging Off.." for hours. Various forums have suggestions about an IE update to fix the problem, driver updates, unsigned drivers, blah blah blah. None of that matters if you cannot get the machine to some kind of command prompt or other useable interface. I’m going to try pulling the battery out and removing all power.
Update: Removing the battery and power cable, then waiting a few minutes before reconnecting power fixed the problem.
