PushScene and PopScene problem.

cocos2d-x C++
#1

Hi all!
I´m a newbie. And I have some problems here.

  1. I have menuScene and infoScene.
    in menuScene, I call pushScene to show infoScene.
    and in infoScene,I call popScene to move back menuScene.
    it´s work well until i call infoScene 3rd time.
    menu~~>info~~>menu~~>info~~>menu->and problem here when i call infoScene. The game close.
  2. How can I popScene without delete current scene?
    Because I want to call them later. It´s long time to reload scene.
  3. How can I exit game when ItemMenu pressed?
