MORE INFORMATION

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

1. Start a new Standard EXE project in Visual Basic. Form1 is created by
  default.

2. Add a ListBox control and a CommandButton to Form1.

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

        Option Explicit

        Private Sub Command1_Click()
           Debug.Print "Appearance property = " & List1.Appearance & _
              " Height property = " & List1.Height
           If List1.Appearance = 0 Then
              List1.Appearance = 1
           Else
              List1.Appearance = 0
           End If
        End Sub

4. Open the Immediate Window. On the Run menu, select Start, or press the F5 key
  to start the program. Click the CommandButton. Note that every CommandButton
  click causes the ListBox height to change.

  If you set the IntegralHeight property of the ListBox to False, the bug
  behavior does not occur.
