// Determines the scope the new cursor will have.
//
// If the RadioButton rbScopeElement is selected, then the cursor
// will only change on the display element.
// 
// If the Radiobutton rbScopeApplication is selected, then the cursor
// will be changed for the entire application
//
private void CursorScopeSelected(object sender, RoutedEventArgs e)
{
    RadioButton source = e.Source as RadioButton;

    if (source != null)
    {
        if (source.Name == "rbScopeElement")
        {
            // Setting the element only scope flag to true
            cursorScopeElementOnly = true;

            // Clearing out the OverrideCursor.  
            Mouse.OverrideCursor = null;
        }
        if (source.Name == "rbScopeApplication")
        {
           // Setting the element only scope flag to false
           cursorScopeElementOnly = false;

           // Forcing the cursor for all elements. 
           Mouse.OverrideCursor = DisplayArea.Cursor;
        }
