+Summary: Enable Panel does not enable it's contents correctly
+
+Description of Problem:
+I have placed some Windows.Form Controls (like checkBox or comboBox) on a
+panel, that is disabled. If the enable state is updated, the controls on
+the panel are not updated correctly. The checkBox for example looks like
+it's enabled, but it's not clickable. 
+
+
+Steps to reproduce the problem:
+1. Create a panel in a Windows.Form, panel.Enabled = false
+2. Add the checkbox to the panel
+3. enable/disable the panel by the program
+
+Actual Results:
+The checkBox turns from grayed-out to normal, but it is not possible to
+change the checkBox state by clicking it. The checkBox is only an example,
+this does happen with other controls, too. Some controls even do not
+reflect the enable state optically correct (like comboBox).
+
+Expected Results:
+The checkBox (and other controls) should be enabled/disabled like the
+parent panel and should reflect the state.
+
+How often does this happen? 
+always
+
+Additional Information:
+SourceCode from VisualStudio.Net with little test application:
+
+using System;
+using System.Drawing;
+using System.Collections;
+using System.Windows.Forms;
+using System.Data;
+
