How to Close Viivi IDE Windows

The minimize-button [ ＿ ] on any window is disabled.
Please click the close-button [ × ] to close each window.

The controller needs to know the visibility of each window, in order to manage it from the window-menu.
However, if a window is hidden, not closed, the controller has no means to know whether the window is visible or invisible.
Therefore, actual closing of the window is needed for the controller to distinguish visible and invisible states of the window.
The author apologizes for any inconvenience this may cause.

The user can also open and close the windows from the "Window" menu on the controller.

Only the controller cannot be closed, but always stays open on the screen.
