+Summary: Clicking a button that was assigned to CancelButton does not close the form
+
+Description of Problem:
+Clicking a button that was assigned to CancelButton does not close the 
+form.
+
+Steps to reproduce the problem:
+1. Compile and run the following program.
+using System.Windows.Forms;
+class TestForm : Form {
+    static void Main() {
+        new TestForm().ShowDialog();
+    }
+    public TestForm() {
+        Button b = new Button();
+        CancelButton = b;
+        Controls.Add(b);
+    }
+}
+2. Click the button.
+
+Actual Results:
+Nothing.
+
+Expected Results:
+The form should close.
+
+How often does this happen? 
+Always.
+
+Additional Information:
+
+Microsoft .NET Framework seems to change DialogResult to Cancel. I suggest 
+to do the same (in Form.cs):
+		public IButtonControl CancelButton {
+			get {
+				return cancel_button;
+			}
+
+			set {
+				cancel_button = value;
+				// Add this line
+				cancel_button.DialogResult = DialogResult.Cancel;
+			}
+		}
