title: Want a drawn circle to follow my mouse in C#
body: <p>First off, I'm a real beginer at C# so please be gentle.</p>
  
  <p>I'm trying to have a circle follow my cursor. I don't want any "trails" to be left behind.</p>
  
  <pre><code>private void Form1_MouseMove(object sender, MouseEventArgs e)
  {
  
      drawCircle(e.X, e.Y);
  
  }
  
  private void drawCircle(int x, int y)
  {
      Pen skyBluePen = new Pen(Brushes.DeepSkyBlue);
      Graphics graphics = CreateGraphics();
      graphics.DrawEllipse(
          skyBluePen, x - 150, y - 150, 300, 300);
      graphics.Dispose();
      this.Invalidate();
  }
  </code></pre>
  
  <p>This works ok, as it draws it and centers on the mouse for every mouse move. However, the "this.Invalidate();" is wrong. It "undraws" the shape after every movement, so I can only see glimpses of it. However, not including it causes every single drawn circle to remain on screen.</p>
  
  <p>How do I get one circle to "gracefully" follow my mouse around, without being too jumpy and without retaining all of the past circles?</p>
