Try changing your setting to never shut down and see if that works.
I'm operating on a XP home os and I can't tell you much beyond that. At any rate the problem I've started having is that whenever the time indicator in the connection status window changes from 23hr and 59min to 1 day, the computer shuts down and reboots itself with no concern for anything that I might be doing or any programs I might have running at the time. Also. the time of day seems to be of no consequence...the computer shuts down as son as the timer reaches 1 day, no matter what time of the day or night it might be. This has only started happening during the past couple of weeks or so, so I feel I may have inadvertently changed a setting somewhere, but I'm not enough of a computer operator to determine what or where the setting might be. Any help would be highly appreciated;
at the age of 77 I'm not ready to go back to school to learn computer theory. Thank you for your time...William Kuwahara
