Application Closes after Wizard Form is closed instead of showing main window

Hi Guys,

So I have created an application that has a custom OnStartUp event handler.

The code within which is similar to this:

m_ConfigurationManager = ConfigurationManager.InitializeInstance(Assembly.GetExecutingAssembly().GetName().Name, 
        Code.StringToSecureString());
if (m_ConfigurationManager.Instance.ReadConfiguration() == false)
{
	Wizard dlg = new Wizard("Application Name");
	if (dlg.ShowDialog() == true)
	{
		m_ConfigurationManager.Configuration = dlg.Result;
		if (m_ConfigurationManager.Instance.Configuration.VerifyData(Code))							
			m_ConfigurationManager.Instance.Configuration.SecureData();
		m_ConfigurationManager.SaveConfiguration();
	}
	else
	{
		Current.Shutdown();
	}
}

if (!m_ConfigurationManager.Instance.ReadConfiguration()) Current.Shutdown();
MainWindow mainWindow = new MainWindow();
mainWindow.Show();

Now the problem I have is this, if my configuration wizard launches and is completed succesffuly instead of the last sections of code:

if (!m_ConfigurationManager.Instance.ReadConfiguration()) Current.Shutdown();
MainWindow mainWindow = new MainWindow();
mainWindow.Show();

runs through, but the application just terminates instead of showing the mainWindow. My understanding is that this is because the message pump is shut down. Is there any what I can stop this from happening?

I have tried calling "Application.Run(new MainWindow)" but this won't compile. I have also tried "this.Run(new MainWindow)" and this results in a dispatch error. (suggested from http://stackoverflow.com/[^])

Has anyone got any idea how I can keep the program running after the wizard closes and run the main window?
