Windows 8 Tip for easily handling an accidental drag-and-drop of an application behind the Taskbar
It's way too easy to accidentally drag and drop a windowed-application to the dead-zone, behind the Taskbar across the bottom. With a mouse, or with a touchscreen. See the video below for a demonstration of the problem and solution, using your mouse cursor.
It's easy enough to just kill the window, which even Task Manager can handle. Or just click the tiny red x from the Thumbnail preview window:
But what if you actually want to see what's going on in that window, or save your work?
1) locate the application that is hiding
