When I connected my TV via HDMI cable to my laptop, a little preview window popped up, all on its own. Now one of these pops up for every app or window I have open--even though I'm no longer connected to the TV. If I right-click on one of them, and choose "end process" it closes that particular app. I would like to know a)what this is b)how to get rid of it (as it's rather annoying) and c)how to keep it from happening again.

Before you ask, when I hit ctrl+alt+del and look at apps, it does not show up. I've attached a screenie-the little windows under the cocks are what I'm talking about.

Thank you.
