I'm sitting here in a hotel room with my family and one of my daughters wanted to play a Yahoo game. I downloaded it and it shrank my screen by 20%. Once they were dine with the game I uninstallled it and my screen remains 20% smaller. I called a friend and he said to hold the "function button and one of the "F" buttons that has an oblong shape on it and this should restore my screen. Problem is I don't have that oblong shape on any of my "F" button and I have held the "function button and hit every "f" key and my screen is still smaller. My buddy has an HP so he is'nt familiar with the Dell keys. Can anyone help me so I can view my ARFCOM pics in regular size?! Thanks...

Look for a key that says "zoom"

Sometimes it's Fn+T
