C# form doesn't close on FormClosing event

After I added the following code to my code-behind, my form doesn't get closed.

private void Form1_FormClosing(object sender, FormClosingEventArgs e) {
    MyThreadingObj.Dispose();
}

protected override void OnFormClosing(FormClosingEventArgs e)
        {            
            base.OnFormClosing(e);
            if (PreClosingConfirmation() == System.Windows.Forms.DialogResult.Yes)
            {
                Dispose(true);
                Application.Exit();
            }
            else
            {
                e.Cancel = true;
            }
        }

        private DialogResult PreClosingConfirmation()
        {
            DialogResult res = System.Windows.Forms.MessageBox.Show(" Do you want to quit?          ", "Quit...", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
            return res;
        }

It sounds like adding the above code prevents your Form from closing. If so then the most likely cause is that the MyTHreadingObj.Dispose() statement is throwing an exception. Try wrapping the statement in a try/catch and seeing if this is the case

try {
  MyThreadingObj.Dispose();
} catch ( Exception e ) { 
  Console.WriteLine(e);
}
