Since u r in the XP forum I assume u r using XP. XP requires a password for scheduler to work. Once u give yourself a password your scheduler should work & move to the right on your task bar.
Although, Norton Anti virus update works every four hours, the virus scan I have scheduled doesn't run??
Also the taskbar icon for task scheduler is on taskbar by the Start button. It used to be by the clock but I can't figure out how to get it there.
