You have designed a form with two content canvases. The window for the first canvas was created implicitly, and you have not changed its default properties. You want users to be able to navigate between the canvases easily while viewing both simultaneously. Therefore, you create a second window, changing only its name from the default properties. However, when you test the form, you find that you are unable to close either window. What must you do to provide this functionality?
