BUG: Line Displays in Title Bar of MDI Child Form

MORE INFORMATION

Steps to Reproduce Behavior

1. Start a new Standard EXE project in Visual Basic. Form1 is created by default.
2. Add an MDI Child Form to the project by completing the following steps:
   
   
   1. From the Project menu, select Add MDI Form. The Add MDI Form dialog box appears with MDI Form highlighted in the New tab.
   2. Click the Open button to add an MDI Form, MDIForm1, to the project.
3. Set the following properties for Form1:

         Property            Setting
         ----------------------------------------
   
         MDIChild            True
   
         BorderStyle         5-Sizable ToolWindow
   						

4. On the Run menu, select Start, or press the F5 key to start the program.
   
   NOTE: A gray line appears below the title bar of the MDI Child window. If you move another window on top of this MDI Child window, the gray line does not repaint.
5. Stop the project and add the following code to the code window of Form1:

         Private Sub Form_Load()
            Me.Height = Me.Height - 15
            Me.Height = Me.Height + 15
         End Sub
   						

6. Run the project again and note that the gray line has disappeared.
