+Summary: Setting FormBorderStyle should not change Bounds
+Description of Problem:
+It seems that setting FormBorderStyle causes a Form to change Bounds.
+Steps to reproduce the problem:
+Compile and run the following program.
+using System.Drawing;
+using System.Windows.Forms;
+class TestForm : Form {
+    static void Main() {
+        Application.Run(new TestForm());
+    }
+    public TestForm() {
+        Rectangle BoundsBeforeBorderStyleChange = Bounds;
+        FormBorderStyle = FormBorderStyle.None;
+        MessageBox.Show((Bounds == 
+    }
+Actual Results:
+Expected Results:
+How often does this happen? 
+Always (on the SVN version).
+Additional Information:
+I noticed the client size remains the same (it should not). The line 
+this.Size = SizeFromClientSize (this.ClientSize);
+in the Form.FormBorderStyle setter looks suspicious.
