+Summary: ScrollableControl should not have a size grip when it doesn't make sense to
+Description of Problem:
+Controls with scrolling activated seem to always display a size grip.
+Steps to reproduce the problem:
+1. 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() {
+        ScrollableControl c = new ScrollableControl();
+        c.AutoScroll = true;
+        c.AutoScrollMinSize = new Size(300, 300);
+        c.Size = new Size(200, 200);
+        Controls.Add(c);
+    }
+2. On MWF notice how the size grip is always displayed. On MS SWF (I 
+tested this on Windows XP, but I think I have seen it on older versions 
+too) try to use the corner of the control as a size grip. It doesn't work. 
+Now resize the form so that its client size is equal to the size of the 
+control. The corner now works. Depending on how I move things, the corner 
+is painted with the window background color, traces of things that were on 
+top of it remain visible, or a size grip is displayed.
+Actual Results:
+The size grip is always displayed.
+Expected Results:
+The size grip is displayed only when the corner of the ScrollableControl 
+is close (I don't know the exact behavior) to the corner of the window. 
+Proper painting is not necessary.
+How often does this happen? 
+Always (in the SVN version).
+Additional Information:
+1. I really don't want MWF to match the painting behavior, I'm just 
+describing what happens on Windows.
+2. Does anybody know how to work around it on MS SWF?
