I don't know what is wrong but the fist time it sends the coordinates
it recieves but the second time it just waits forever
I don't get it
this is my code

}
// Clear the screen with red color
App.Clear();
App.Draw(sf::Shape::Rectangle(x,y,x+32,y+32,sf::Color::Red));
// Display window contents on screen
App.Display();
}
return EXIT_SUCCESS;
}
Ist in a infinite loop so it must work
Thanks
