This will bind to leftmouse-down, which is different from clicking a
button.  If you want to simulate a real button click with event
bindings, you will need to set a flag on ButtonPress-1, then in
ButtonRelease-1 check for the flag, check to see if the mouse is
within the button, and then activate your callback.

Something else you could try (which I haven't tested) --- instead of
box.cancel.bind, do box.cancel.config(command= ...).
