title: c# picturebox dock problems
body: <p>I wish to dock my picturebox to right-top corner of my form, but when I use<br>
    <code>pictureBox1.Dock = DockStyle.Right;</code><br>
  the image from picturebox is in the right place, but its background color creates a streatched stripe for whole height of my form. It doesn't appera if I use<br>
   <code>pictureBox1.Dock = DockStyle.Left;</code></p>
  
  <p>I have no idea why is it so, can anyone help me?</p>
  
  <p>I wish it was sticked to right top corner and when I try to resize the window to smaller - make it disappear, when I try to resize  to bigger window - keep it still sticked to righttop corner.</p>
