New Post: problem with ShowDialog()

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        axMap1.MouseDownEvent +=new AxMapWinGIS._DMapEvents_MouseDownEventHandler(axMap1_MouseDownEvent);
    }

    void axMap1_MouseDownEvent(object sender, AxMapWinGIS._DMapEvents_MouseDownEvent e) {
        Form2 form2 = new Form2();
        form2.ShowDialog();
    }
}
