全屏模式下设备丢失的问题

有这么几个函数C/C++ code

  QFAPI  void    D3D9FrameRender(HWND hWnd,FLOAT fTimeDelta,int state);
  QFAPI  void    D3D9FrameCleanup();
  QFAPI  void LoadingResource();
  void static OnLostDevice( void );
  void static OnResetDevice( void );
  void  static  InitDevice(void);

C/C++ code

void  QFDeviceManager9::OnLostDevice( void )
        {
            g_pSprite -> OnLostDevice(); 
            g_pTextFPS -> OnLostDevice();
            g_pTextnihao -> OnLostDevice();
            
        }
        void  QFDeviceManager9::OnResetDevice( void )
        {
            if (FAILED(g_pd3dDevice->Reset( & d3dpp)))
            {
                return ;
            }

            g_pSprite -> OnResetDevice();
            g_pTextFPS -> OnResetDevice();
            g_pTextnihao -> OnResetDevice();
            InitDevice();
        }
        void  QFDeviceManager9::InitDevice(void)
        {



            //设置光照
            g_pd3dDevice->SetRenderState(D3DRS_LIGHTING, false);
            g_pd3dDevice->SetRenderState(D3DRS_AMBIENT, D3DXCOLOR(0.4f, 0.4f, 0.4f, 1.0f));

            // 设置虚拟摄像机
            g_pCamera = new CCamera(g_pd3dDevice);
            g_pCamera->ResetCameraPos(&D3DXVECTOR3(0.0f, 30.0f, -100.0f));
            g_pCamera->ResetViewMatrix();

            D3DXMATRIX matProj;
            D3DXMatrixPerspectiveFovLH(&matProj, D3DX_PI / 4.0f, 1.0f, 1.0f, 2000.0f);
            g_pCamera->ResetProjMatrix(&matProj);
        }

检查设备丢失C/C++ code

            hr  =  g_pd3dDevice-> Present(NULL, NULL, NULL, NULL);
            if (hr  ==  D3DERR_DEVICELOST)
            {
                if (g_pd3dDevice-> TestCooperativeLevel()  ==  D3DERR_DEVICENOTRESET)
                {
                    OnLostDevice();
                    OnResetDevice();
                }

我用debug配置的时候运行正常...换成release后就会崩溃...地址在d3dx9_43.dll中..有高人能知道原因么.......

写的不错，谢谢
