+Summary: MONO Beta 1 Bug: System.Drawing.Bitmap not reading from Stream
+
+Description of Problem:
+I can load a Bitmap from a file using: new Bitmap("RSP.gif").  However in 
+my app I am reading in the bitmap as a stream from another server.  MONO 
+currently throws a NotImplemented exception stopping this program from 
+running on MONO, but works fine in MS.NET.   
+
+Steps to reproduce the problem:
+using System;
+using System.Drawing;
+using System.IO;
+
+public class test
+{
+  public static void Main()
+  {
+    Console.WriteLine("Loading Image via File");
+    Bitmap bitmap = new Bitmap("RSP.gif"); // THIS WORKS
+    Console.WriteLine("Done.  Now loading image via Stream");
+    Stream imageStream = File.OpenRead("RSP.gif");
+    Bitmap bitmap2 = new Bitmap(imageStream); // NOT IMPLEMENTED Exception
+  }
+}
+
+Actual Results:
+Works fine in MS.NET.  In MONO the second attempt fails when trying to 
+load the Bitmap from a Stream:
+
+Unhandled Exception: System.NotImplementedException: Feature not 
+implemented.
+in <0x001bd> System.Drawing.GDIPlus:CheckStatus (System.Drawing.Status)
+in <0x000a0> System.Drawing.Image:InitFromStream (System.IO.Stream)
+in <0x00056> (wrapper remoting-invoke-with-check) 
+System.Drawing.Image:InitFromStream (System.IO.Stream)
+in <0x0001c> System.Drawing.Bitmap:.ctor (System.IO.Stream,bool)
+in <0x00012> System.Drawing.Bitmap:.ctor (System.IO.Stream)
+in <0x00056> (wrapper remoting-invoke-with-check) 
+System.Drawing.Bitmap:.ctor (System.IO.Stream)
+in <0x00080> test:Main ()
+
+Expected Results:
+Should be able to load Bitmap from a stream.
+
+How often does this happen? 
+All the time on MONO Beta 1.
