OnMarkerClick events fires multiple times

Question

I try to popup a messagebox when the marker was left-clicked. When the marker was clicked, the event was fired, the popup was showing, but it fires multiple times (2 times).

This is my code

private void gmap_mainMap_OnMarkerClick(GMapMarker item, MouseEventArgs e)
{
    if (e.Button == System.Windows.Forms.MouseButtons.Left && item.IsMouseOver){
        MessageBox.Show("Marker clicked", "Information");
    }
}

Anyone have idea why the event keeps firing multiple times? Thanks!

just to make sure, you can do this:

private bool MarkerWasClicked = false;

private void gmap_mainMap_OnMarkerClick(GMapMarker item, MouseEventArgs e)
{
    MarkerWasClicked = false;

    if (MarkerWasClicked == false){
        if (e.Button == System.Windows.Forms.MouseButtons.Left && item.IsMouseOver){
            MessageBox.Show("Marker clicked", "Information");
            MarkerWasClicked = true;
        }
    }
}
