+Summary: Form ClientRectangle.Size Ignores Menu and Scroll bar.
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+With .NET the ClientRectangle.Size does not subtract the Menu bar or the
+Scrollbar area of the form.
+
+The following program with a Menu and a Scroll bar can be used to
+illustrate the problem:
+
+using System;
+
+using System.Drawing;
+
+using System.Collections;

+
+			}
+

+

+
+}
+
+
+
+Steps to reproduce the problem:
+1. Compile and execute the program.
+2. Using the Mouse, move the cursor around the screen. When you get within
+50 pixels of any border of the form the cursor will change to an IBeam.
+When you get to the end of the ClientRectangle area the cursor will change
+ back to an arrow. 
+
+With .Net this will happen if you cross the menu bar on the top, or the
+Scroll bar on the right of the form. With Mono the IBar remains to the end
+of the Form, ignoring the menu bar and the scroll bar.
+3. 
+
+Actual Results:
+Ibeam cursor does not change to an arrow when above the menu bar, or to the
+right of the scroll bar.
+
+Expected Results:
+Ibeam cursor should change to an Arrow when cursor is above the bottom of
+the menu bar, and to the right of the left most edge of the scroll bar.
+
+How often does this happen? 
+Always
+
+Additional Information:
+
+Mono is from SVN
