Hello,
I was just wondering how I could get my screen back to normal.I pressed a button on my keyboard a few minuets ago and was shocked to find that there was no toolbar, at the top or bottom my screen. Whenever I hover over the top of my screen, however; my toolbar comes back. My screen is now being taken up by just the page I'm on and nothing else. Please help.
