The information in this article applies to:

- Microsoft Visual Basic Learning Edition for Windows, versions 5.0, 6.0 
- Microsoft Visual Basic Professional Edition for Windows, versions 5.0, 6.0

SYMPTOMS
========

When a project has two or more visible forms and a message box is displayed, one
or more forms fall to the background, possibly behind other forms. This behavior
did not occur in Visual Basic version 4.0.

CAUSE
=====

This problem occurs when a MsgBox is displayed from a form that has the
following properties set:

     ShowInTaskBar = False
     BorderStyle = 3-FixedDialog

RESOLUTION
==========

Change the ShowInTaskBar property to True or the BorderStyle property to
something other than 3-FixedDialog.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. We are researching this bug and will post new
information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION
================

Steps To Reproduce
------------------

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

2. Add a new form (Form2) to the project.

3. In the Form1 Click event, place the following code:

        Private Sub Form1_Click()
           Form2.Show
        End Sub

4. In the Form2 Click event, place the following code.

        Private Sub Form2_Click()
           MsgBox "Where's the Form?"
        End Sub

5. Change the BorderStyle property of Form2 to number 3-Fixed dialog.

6. Change the ShowInTaskBar property of Form2 to False.

7. Press the F5 key to run the project.

8. Click on Form1 and then click Form2. The MsgBox is displayed and then Form2
  drops to the background, possibly behind Form1.
