double click button of a popup window

hello,every one,i found a problem that ,i create a popup window with a button to close the window.
when double click the button on the window quickly,the page will dead.

code:

@Override
    protected void init(VaadinRequest request) {
        
        final VerticalLayout layout = new VerticalLayout();
        layout.setMargin(true);
        setContent(layout);

        Button btn = new Button();
//

        btn.addClickListener(new ClickListener() {

            @Override
            public void buttonClick(ClickEvent event) {
                VerticalLayout layout = new VerticalLayout();
                Button btn2 = new Button();
                layout.addComponent(btn2);
                
                Window window = new Window("test", layout);
//                window.setDraggable(false);
                V7UI.this.addWindow(window);
                window.center();
                btn2.addClickListener(new ClickListener() {
                    
                    @Override
                    public void buttonClick(ClickEvent event) {
                        window.close();
                    }
                });
                window.bringToFront();
            }
        });
        layout.addComponent(btn);
    }

i found this is because when i double click the button ,vaadin will think as i will drag the window , so that the method

  private void beginMovingWindow(Event event) {
        if (draggable) {
            showDraggingCurtain();
            dragging = true;
            startX = WidgetUtil.getTouchOrMouseClientX(event);
            startY = WidgetUtil.getTouchOrMouseClientY(event);
            origX = DOM.getAbsoluteLeft(getElement());
            origY = DOM.getAbsoluteTop(getElement());
            DOM.setCapture(getElement());
            DOM.eventPreventDefault(event);
        }
    }

of Class VWindow  will be called ,will create a DIV draggingCurtain,which cause the problem,how do i solve or avoid this problem,thank you very much,forgive my poor english

Hi,

Maybe Button.setDisableOnClick(boolean) could solve your issue.
