Graphics / Clicking app titlebar makes objects skip

I a simple program that just make a 32x32 ball bounce around the screen and when I click and hold the the application's titlebar the ball appears to be still, but when I release the ball seems to go past the set boundaries.

Code: [Select]


#include <SFML/Graphics.hpp>

int vx = 500;
int vy = 150;
const int windowWidth = 800;
const int windowHeight = 600;
const int ballSize = 32;


int main()
{
    sf::RenderWindow App(sf::VideoMode(800,600,32), "Physics Simulation");

    App.SetFramerateLimit(60);
    const sf::Input& Input = App.GetInput();

    sf::Image ballImg;

    if(!ballImg.LoadFromFile("Ball.png"))
        return EXIT_FAILURE;

    sf::Sprite Ball(ballImg);
    Ball.SetPosition(400,600-32);

    ///***
    while(App.IsOpened())
    {
      if(Ball.GetPosition().y > windowHeight-ballSize)
         vy *= -1;
if(Ball.GetPosition().y < 0)
vy *= -1;
if(Ball.GetPosition().x > windowWidth-ballSize)
vx *= -1;
if(Ball.GetPosition().x < 0)
vx *= -1;

Ball.Move(vx*App.GetFrameTime(), vy*App.GetFrameTime());

        sf::Event Event;
        while(App.GetEvent(Event))
        {
            if(Event.Type == sf::Event::Closed)
                App.Close();
        }

        App.Clear(sf::Color(100, 149, 237));
        App.Draw(Ball);
        App.Display();

    }
    return EXIT_SUCCESS;
}
