using highgui - difficulties with namedWindow

Dear all,

I am new with openCV, I am trying to use the graphical interface highgui.

I have tried the following very simple piece of code, which is compiled properly, but when I run it I get an error message like

"Unhandled exception at 0x774f15de in try1.exe: 0xC0000005: Access violation reading location 0xcccc006f."

What am I doing wrong?

Here is the code:

// try1.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
//#include "myfunc.h"

using namespace std;
using namespace cv;

int _tmain(int argc, _TCHAR* argv[])
{
   namedWindow("Hello");
   return 0;
}

I don't know if it matters, I have created a C++ console application with Visual Studio 10.

I thank you for your very kind help.
