v1.0.6

• Window mode now shows which window is actually being scoped (thanks to
  DatTestBench for the request): the title bar appends the target window's
  title while it is being scoped, and the Capture section shows a
  "Scoping: ..." confirmation under the picker button. When nothing is
  cropped — no window picked yet, the window closed, or it sits wholly off
  the captured monitor — both readouts say so instead of naming a window
  that isn't being scoped.
• Fixed: after a scoped window closed, Windows could reuse its window handle
  for an unrelated window, silently switching the scopes to that window. The
  pick is now tied to the original window's process and lapses cleanly to
  the full monitor instead.
