I have the following class:

[Serializable]
[XmlRoot ( ElementName = "TextData", IsNullable = false)]
public class TextData
{
    private System.Drawing.Font fontColor;

    [XmlAttribute ( AttributeName = "Font" )]
    public System.Drawing.Font Font { get; set; }

    [XmlAttribute ( AttributeName = "FontColor" )]
    public System.Drawing.Color FontColor { get; set; }

    [XmlAttribute ( AttributeName = "Text" )]
    public string Text { get; set; }

    public TextData ( )
    {
    } // End of TextData
} // End of TextData

And Im attempting to save it with the following code:

    // Create our font dialog
    FontDialog fontDialog = new FontDialog ( );
    fontDialog.ShowColor = true;

    // Display the dialog and check for an ok
    if ( DialogResult.OK == fontDialog.ShowDialog ( ) )
    {
        // Save our changes for the font settings
        if ( null == Properties.Settings.Default.MainHeadlineTextData )
        {
            Properties.Settings.Default.MainHeadlineTextData = new TextData ( );
        }
        Properties.Settings.Default.MainHeadlineTextData.Font = fontDialog.Font;
        Properties.Settings.Default.MainHeadlineTextData.FontColor = fontDialog.Color;
        Properties.Settings.Default.Save ( );
    }

Everytime I load the the application, the Properties.Settings.Default.MainHeadlineTextData is still null. Saving does not seem to take effect. I read on another post that the class must be public and it is. Any ideas why this would not be working properly?
