Can not close program by click close button

[slipperstree]

When click close button, window will disapred but the program is still alive in backgroud.

If this is a mac, it is supposed to happen, or else if this is on a Windows-based OS, this isn't supposed to happen. It still happens because of a temporary window that is closed as soon as the main app is created in order to allow for multi-window support.

Could be fixed by adding a quit() statement after the close button is pressed on any of the windows.
