+Summary: Button displays image even if FlatStyle is set to System
+Description of Problem:
+Button displays Image even if FlatStyle is set to System.
+Steps to reproduce the problem:
+Compile and run the following program.
+using System.Windows.Forms;
+class TestForm : Form {
+    static void Main() {
+        Application.Run(new TestForm());
+    }
+    public TestForm() {
+        Button Button = new Button();
+        Button.FlatStyle = FlatStyle.System;
+        Button.Image = Icon.ToBitmap();
+        Controls.Add(Button);
+    }
+Actual Results:
+A button with an image.
+Expected Results:
+No image displayed on the button.
+How often does this happen? 
+Additional Information:
+I believe that on Microsoft .NET Framework (v. 1.1) this limitation is due 
+to the fact that the controls with FlatStyle set to FlatStyle.System are 
+not drawn by the usual Common Controls library, but by a special, themed 
+version (Windows XP, v. 6.0). See also Application.EnableVisualStyles in 
+the .NET Framework 2.0 documentation. Anyway, FlatStyle.System should not 
+be used, so this should not reduce functionality for new applications, 
+however older applications may rely on this behaviour.
