+Summary: Forms with menus do not work
+
+Steps to reproduce the problem:
+Compile and run the following program.
+using System.Windows.Forms;
+class Test {
+    static void Main() {
+        Form f = new Form();
+        f.Menu = new MainMenu();
+        Application.Run(f);
+    }
+}
+
+Actual Results:
+NullReferenceException in XplatUIWin32.PaintEventStart, in the line
+hwnd.drawing_stack.Push (hdc);
+in the else block, caused by Hwnd.windows not containing at that time the 
+Hwnd for the handle.
+PaintEventStart is called from Form.WndProc, handling WM_NCPAINT.
+WndProc is called from XplatUIWin32.CreateWindow, in the Win32CreateWindow 
+call, before the line
+hwnd.ClientWindow = WindowHandle;
+which adds the Hwnd to Hwnd.windows.
+
+How often does this happen? 
+Always, on the SVN version.
