Why do you nead w WebBrowser. Maybe WebRequest would be good for you if
you don't need to show it.
If i were you I would probably use a background worker to do the job.

Forget about the control.

Take control of your code.

Here is a sample to get your started.

It may not be perfect, but it will get you in the right direction.

 public void WriteTextFile(string Url, string FilePath, long BufferSize )
 {

  try
  {

   //create a web request
   HttpWebRequest oHttpWebRequest = null;
   oHttpWebRequest = (HttpWebRequest) System.Net.WebRequest.Create(Url);

   //set the connection timeout
   oHttpWebRequest.Timeout = 60;// m_ConnectTimeout;

   //create a response object that we can read a stream from
   HttpWebResponse oHttpResponse = (HttpWebResponse)
oHttpWebRequest.GetResponse();

   long workingbuffersize = 1;

   //if we don't get back anything from the response, throw and exception
   if (oHttpResponse == null)
   {
    throw new Exception("Url is missing or invalid.");
   }

   StreamReader sr =null;
   StreamWriter sw=null;

   //Define the encoding type
   try
   {
    //see if the page will give us back an encoding type
    if (oHttpResponse.ContentEncoding.Length  > 0)
     m_enc = Encoding.GetEncoding(oHttpResponse.ContentEncoding);
    else
     m_enc = Encoding.GetEncoding(1252);
   }
   catch
   {
    // *** Invalid encoding passed
    m_enc = Encoding.GetEncoding(1252);
   }

   //create a stream reader grabbing text we get over HTTP
   sr = new StreamReader(oHttpResponse.GetResponseStream(),m_enc);

   //set the variable that we will use as a buffer to store characters in
while the file is downloading
   char[] DownloadedCharChunk = new char[BufferSize];

   //go ahead and create our streamwriter to write our file
   sw = new StreamWriter(FilePath,false,m_enc);

   sw.AutoFlush = false;

   //when the working buffer size hits 0 then we know that the file has
finished downloading
   while (workingbuffersize > 0)
   {
    //set the working buffer size based on the length of characters we
receive from the stream
    //we will also set DownloadedCharChunk to the set of characters we
recieve from the stream
    workingbuffersize = sr.Read(DownloadedCharChunk,0,(int) BufferSize);

    if (workingbuffersize > 0)
    {
     //write DownloadedCharChunk to the file on disk
     sw.Write(DownloadedCharChunk,0,(int) workingbuffersize );
    }

   } // while

   //sr.Close(); //moved to finally block
  // sw.Close(); //moved to finally block

  }

finally

   if(null!=sr)

sr.Close();
