+Summary: ContainerControl should not receive focus
+
+The following example demonstrates that either UserControl or Form steals a
+focus from its child Button:
+
+using System;
+using System.Drawing;
+using System.Windows.Forms;
+
+public class Test : Form
+{
+        public static void Main ()
+        {
+                Application.Run (new Test ());
+        }
+
+        public Test ()
+        {
+                Button b = new Button ();
+                UserControl p = new UserControl ();
+                p.Dock = DockStyle.Top;
+                p.BackColor = Color.Red;
+                p.Controls.Add (b);
+                Controls.Add (p);
+        }
+}
+
+
+Steps to reproduce the problem:
+1. Build and run the above.
+2. Select the button (btw it should not be required since the button should
+have the initial focus).
+3. Click anywhere else on the form than the button.
+
+Actual Results:
+
+The focus on the button is lost.
+
+Expected Results:
+
+The focus should remain on the button.
+
+
+This means that either UserControl or Form should not steal the focus on
+the button.
+
+Both UserControl and Form are derived from ContainerControl.
+
+If you replace UserControl with Panel (derived from ScrollableControl),
+this problem does not happen.
