I have strange problem using mouse with cocos2d-x.I am using the code from the cocos2d-x sample test but I get negative coordinates along Y-axis.(Coordinate along X-axis is corect)Same is true with code from the programmer's guide.Please help as the code included in the sample test of Cocos2d-x is working correct but i am new to cocos2d-x and don't now much about how the test are working and why mine is not.Any help on this is greatly appreciated.I checked the forums with people having the same issue and adding offsets to get it work for themselves.Any please help about  the INPUT test code which comes with cocos2d-x will be great.

Here is the code i am using→

Header file->

#include "cocos2d.h"


class myMouseEventTest : public cocos2d::Scene
{
public:
    CREATE_FUNC(myMouseEventTest);
    myMouseEventTest();
    ~myMouseEventTest();

    void onMouseDown(cocos2d::Event* event);
    void onMouseUp(cocos2d::Event* event);
    void onMouseMove(cocos2d::Event* event);
    void onMouseScroll(cocos2d::Event* event);


private:
    cocos2d::Label*   _labelAction;
    cocos2d::Label*   _labelPosition;
    cocos2d::EventListenerMouse* _mouseListener;
};

I am running the Direcotr With this scene and and i get negative coordniates(along Y) but corect coordinates along the X-axis.Tried both on mac and PC(windows 8.1).
