Message box appears minimized

Hi there,

I am showing a message box like this:

public Home()
        {
            InitializeComponent();
            folderBrowserDialog1.SelectedPath = TSMLfolder;
            DialogResult res = folderBrowserDialog1.ShowDialog();
            if (res == DialogResult.OK)
            {
                TSMLfolder = folderBrowserDialog1.SelectedPath;
                MessageBox.Show("You are now working in the folder " + TSMLfolder, "Environment Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
        }

The message box appears minimized. I am on Vista. Am I not using the proper method?

Thanks,
Emilie
