SYMPTOMS
========

A check mark only appears next to the previously selected item in a second level
menu. The check mark appears next to the correct item only after the mouse
passes over that item.

RESOLUTION
==========

To work around this issue, set the Checked property of a second level menu item
in the top level menu event rather than the second level menu event.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug has been fixed in Visual Basic 6.0.

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

1. Start 16-bit or 32-bit Visual Basic 4.0, or if it is already running, click
  New Project on the File menu.

2. Use the Menu Editor to add the following menu items. Note that the Blue,
  Green, and Cyan should appear only if you click Color, and Color appears if
  you click Options. Click Menu Editor from the Tools menu.

     Caption            Name                   Index
     -------            ----                   -----
     Options          mnuOption
       Color          mnuOptionsColor
         Blue         mnuOptionsColorArray       0
         Green        mnuOptionsColorArray       1
         Cyan         mnuOptionsColorArray       2

3. Copy the following code to the Code window of the Form1 form:

        Option Explicit
        Dim ncol As Integer

        Private Sub mnucol_Click(Index As Integer)
           ncol = Index
           BackColor = QBColor(Index + 1)
        End Sub

        Private Sub mnuColor_Click()
           Dim i As Integer
           For i = 0 To 2
              If i = ncol Then
                 mnuCol(i).Checked = True
              Else
                 mnuCol(i).Checked = False
              End If
           Next
        End Sub

        Private Sub mnuOptions_Click()
           'Uncomment the following lines for workaround
           'Dim i As Integer
           'For i = 0 To 2
              'mnucol(i).Checked = (i = ncol)
              'Next
            End Sub

4. On the Run menu, click Start or press the F5 key to start the program. From
  the Options menu, click Color and note that a second level menu appears.
  Choose a color to change the background color of the form. Click Color again
  from the Options menu and choose another color. Click Color a third time and
  note that a check mark appears next to the original color you selected. Move
  the mouse over the previously selected color and note that a check mark
  appears on the correct choice.
