My taskbar will not display on my screen not matter what I try. I am running Windows Vista. I have two profiles on my laptop. My wife's and mine. When I switch to my wife's profile, the taskbar displays just fine. I go into my control panel to Appearances and go to Taskbar Settings. I click it and nothing happens. So I can't access it to see if it is in AUTO HIDE. When I do the same on my wife's profile, it works just fine.
