G4P and P3D - can not input text into text field

Hello, I can not input text into text field on GUI window created by G4P in case if the main (sketch) window uses P3D. Please help to solve this issue.

Example code: `

    // Need G4P library
    import g4p_controls.*;


    public void setup(){
      size(480, 320, P3D);
      createGUI();
      customGUI();
      // Place your setup code here

    }

    public void draw(){
      background(230);

    }

    // Use this method to add additional statements
    // to customise the GUI controls
    public void customGUI(){

    }

`

synchronized public void win_draw1(GWinApplet appc, GWinData data) { //_CODE_:window1:248571:
  appc.background(230);
} //_CODE_:window1:248571:

public void textfield2_change1(GTextField source, GEvent event) { //_CODE_:textfield2:400022:
  println("textfield2 - GTextField >> GEvent." + event + " @ " + millis());
} //_CODE_:textfield2:400022:

public void createGUI(){
  G4P.messagesEnabled(false);
  G4P.setGlobalColorScheme(GCScheme.BLUE_SCHEME);
  G4P.setCursor(ARROW);
  if(frame != null)
    frame.setTitle("Sketch Window");
  window1 = new GWindow(this, "Window title", 0, 0, 240, 120, false, JAVA2D);
  window1.addDrawHandler(this, "win_draw1");
  textfield2 = new GTextField(window1.papplet, 40, 45, 160, 30, G4P.SCROLLBARS_NONE);
  textfield2.setOpaque(true);
  textfield2.addEventHandler(this, "textfield2_change1");
}

// Variable declarations

GWindow window1;
GTextField textfield2;
