Vanity with out works is dead

I'm on my pretty new computer and I am at it's mercy! I have to settle for what ever it pops up. I can't get out of the program I'm on. My friend Candace helped me yesterday but I am still at a loss to master the simplest things. I keep returning to my old Acer computer, but I think it is about to die. My new computer has a beautiful sky blue cover and key board cover to match. I can't make it work worth bean, but it sure look good.
