Mouse not disappearing when calling nifty.exit()

Troubleshooting gui
1

I have a nifty main menu. Whe the button “Campagin” is pressed, I call nifty.exit() to remove the main menu and enable the flycam. Nifty menu disappears, but mouse keeps being shown and when I move it, the scene moves, but mouse isn’t trapped in the middle of the screen…

My main menu appstate:
[java]
public class StartScreenState extends AbstractAppState implements ScreenController{
private Nifty nifty;
private Screen screen;
private MWApp app;
NiftyJmeDisplay display;

public StartScreenState(NiftyJmeDisplay display){
    super();
    this.display = display;
}

@Override
public void initialize(AppStateManager stateManager, Application app) {
    super.initialize(stateManager, app);
    this.app = (MWApp)app;
    //TODO: initialize your AppState, e.g. attach spatials to rootNode
    //this is called on the OpenGL thread after the AppState has been attached
}

@Override
public void update(float tpf) {
    //TODO: implement behavior during runtime
}

@Override
public void cleanup() {
    super.cleanup();
    //TODO: clean up what you initialized in the initialize method,
    //e.g. remove all spatials from rootNode
    //this is called on the OpenGL thread after the AppState has been detached
}

public void bind(Nifty nifty, Screen screen) {
    this.nifty = nifty;
    this.screen = screen;
}

public void onStartScreen() {
    //throw new UnsupportedOperationException("Not supported yet.");
}

public void onEndScreen() {
    //throw new UnsupportedOperationException("Not supported yet.");
}

public void quit(){
    app.stop();
    System.exit(0);
}

public void settings(){
    //TODO Switch to settings screen
    System.out.println("No settings yet...");
}

public void campagin(){
    //TODO
    System.out.println("Campagin clicked.");
    nifty.exit();
    app.getFlyCam().setEnabled(true);
}

}
[/java]

Meh, forget. Calling mouseInput.setCursorVisible(false); in the SimpleApplication did the job.
