Steps to Reproduce Behavior
---------------------------

1. Start a New ActiveX Control Project. UserControl1 is created by default.

2. From the Tools menu, click the Menu Editor. Add the following three menu
   items:

    - 

    - Caption : Menu1
    - Name : Menu1
    - NegotiatePosition = Left

    - 

    - Caption : SubMenu1
    - Name : SubMenu1
    - Click the Right Arrow button to make it a SubMenu.

    - 

    - Caption : Menu2
    - Name : Menu2
    - NegotiatePostion = Left

3. Add a CommandButton (Command1) to the UserControl. Add the following code to
   the General Declarations section of UserControl1:

         Private Sub Command1_Click()
            Menu1.Caption = "Modified"
         End Sub

4. Close all open windows on Project1.

5. From the File menu, click Add Project to add a New Standard .exe Project.
   Form1 is created by default.

6. Place an instance of UserControl1 to Form1, and run the project.

7. Click the CommandButton on the UserControl. The caption of Menu1 does not
   change.

8. To work around the problem replace the code in UserControl1 with the
   following:

         Private Sub Command1_Click()
            Menu1.Caption = "Modified"
            UserControl.Enabled = False
            UserControl.Enabled = True
            UserControl.SetFocus
            DoEvents
         End Sub

9. Close Project1 and repeat Step 7. The menu caption is updated.
