+Summary: Form.Visible should return true during OnLoad
+Description of Problem:
+The Visible property of a Form returns false when called from the OnLoad 
+Steps to reproduce the problem:
+Compile and run the following program.
+using System;
+using System.Diagnostics;
+using System.Windows.Forms;
+class TestForm : Form {
+    static void Main() {
+        Application.Run(new TestForm());
+    }
+    protected override void OnLoad(EventArgs e) {
+        base.OnLoad(e);
+        Debug.Assert(Visible);
+    }
+How often does this happen? 
+Always (on the SVN version).
+Additional Information:
+I think the problem is in Control.SetVisibleCore. is_visible should be set 
+before calling CreateControl.
