C# Web browser navigation

I have open browsers on my application which load in data using the default web browser.

//Set the function and display the browsers we're using (per screen)
browsers[index].Width = screens[index].Bounds.Width;
browsers[index].Height = screens[index].Bounds.Height;
browsers[index].Location = new System.Drawing.Point(screens[index].Bounds.X, screens[index].Bounds.Y);

browsers[index].Navigate(new Uri(lines[index]));
browsers[index].Show();

Now my problem is that when you click a link on the page, it leaves my application and openes a new browser completely. Any way of getting out of this?

lines contains an array of URL's and browsers is an array of web pages to load up on different screens.

If I am not wrong this is happening because of 'TARGET = "_blank"' , I would try removing this this from the tag before the content is rendered. 

private void Browser_ProgressChanged(object sender, WebBrowserProgressChangedEventArgs e)
{
    var webBrowser = (WebBrowser)sender;
    if (webBrowser.Document != null)
    {
        foreach (HtmlElement tag in webBrowser.Document.All)
        {
            if (tag.Id == null)
            {
                tag.Id = String.Empty;
                switch (tag.TagName.ToUpper())
                {
                    case "A":
                    {
                        tag.MouseUp += new HtmlElementEventHandler(link_MouseUp);
                        break;
                    }
                }
            }
        }
    }
}


private void link_MouseUp(object sender, HtmlElementEventArgs e)
{
    var link = (HtmlElement)sender;
    mshtml.HTMLAnchorElementClass a = (mshtml.HTMLAnchorElementClass)link.DomElement;
    switch (e.MouseButtonsPressed)
    {
        case MouseButtons.Left:
        {
            if ((a.target != null && a.target.ToLower() == "_blank") || e.ShiftKeyPressed || e.MouseButtonsPressed == MouseButtons.Middle)
            {
                AddTab(a.href);
            }
            else
            {
                CurrentBrowser.TryNavigate(a.href);
            }
            break;
        }
        case MouseButtons.Right:
        {
            CurrentBrowser.ContextMenuStrip = null;
            var contextTag = new ContextTag();
            contextTag.Element = a;
            contextHtmlLink.Tag = contextTag;
            contextHtmlLink.Show(Cursor.Position);
            break;
        }
    }
}
