You need to use a global mouse hook via SetWindowsHookEx() in order to do
that.  Global hooks must be placed in a DLL.  The hook can use
WindowFromPoint() to detect when the mouse is not over any window other than
the Desktop.  Using the GetDestktopWindow() function to get the Desktop's
window handle, you can then issue standard ListView messages to it in order
to get the hit-test and icon information as needed.
