Want to capture a screen from Metro or one of its apps? If you try a Windows Desktop screen capture program, it may not work --- press the hot key for screen capture and nothing may seem to happen. Here's a workaround. Press the hot key, then get to the Metro desktop and click Desktop. At that point, you'll be sent back to the Metro screen you wanted to capture, and your screen capture program will spring into action --- at least, that's what happens to me using Snag-It. Your experience may differ.
        There's an even more awkward way. When you're inside a Metro app, put your mouse pointer at the bottom left of the screen and then click the Share button. You'll then be prompted to share a screen capture using Metro's Socialite app for Facebook. This technique won't work on the main Metro interface itself, and may not work for every app.
