title: C# Winforms: GroupBox not resizing
body: <p>I have two <code>GroupBoxes</code> on the left side of one of my <code>TabControls</code>, call them GroupBox A (top left), and GroupBox B (bottom left). The GroupBoxes do not resize like I would hope. </p>
  
  <p><strong>Example:</strong>
  When I resize the main form that has the TabControls with my mouse, or maximize it, or move it to a screen with lower resolution, GroupBox B keeps its width / height. This causes GroupBox B to draw over GroupBox A, kind of like a 'always on top' effect.</p>
  
  <p><strong>Desired:</strong>
  Would like both GroupBoxes to resize according to one another / proporitionally and fit the area they are given. </p>
  
  <p>Ideas?</p>
