           Summary: ProcessCmdKey() fails in Mono 2.4.2.3 (works in
                    2.4.2.1)
    Classification: Mono
           Product: Mono: Runtime
           Version: 2.4.x
          Platform: x86
        OS/Version: Red Hat 7.0

I believe this is a regression bug when going from 2.4.2.1 to 2.4.2.3. The
following simple WinForms app will fail on RedHat:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace KeyPress
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {

            switch (keyData)
            {
                case Keys.F11:
                    F11ButtonPressed();
                    break;
                case Keys.F12:
                    F12ButtonPressed();
                    break;
            }

            return true;
        }

        private void F11ButtonPressed()
        {
            this.Text = "F11 button pressed";
        }

        private void F12ButtonPressed()
        {
            this.Text = "F12 button pressed";
        }

    }
}

Reproducible: Always

Steps to Reproduce:
1. Compile + run above app
2.
3.
Actual Results:  
Works on Microsoft runtime, fails on Mono 2.4.2.3 + RedHat i.e. application
locks up.

Expected Results:  
WIndow text should change to reflect the key that was pressed.
