Steve
Are you referring to the 'Find' window from Windows Spy++?
If so, then that's not a draggable window at all: the application
changes the cursor, and captures the mouse (see SetCapture()) so that it
gets mouse move events for the mouse outside it's window borders. It
then hit-tests on each mouse move to find the handle to any window under
the mouse, gets the window co-ordinates (GetWindowRect() on the handle
found), and then draws the rectangle around the window by drawing into
the 'DISPLAY' DC (See CreateDC).
Of course, it may do it entirely differently, but that's how I would do it.
