-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual Basic Learning Edition for Windows, version 5.0 
- Microsoft Visual Basic Professional Edition for Windows, version 5.0 
- Microsoft Visual Basic Enterprise Edition for Windows, version 5.0 
- Microsoft IntelliPoint software, version 2.2 
-------------------------------------------------------------------------------

SYMPTOMS
========

The Complete Word list box or the Auto List Members list box may close
unexpectedly when using the universal scrolling feature of the IntelliPoint
Software version 2.2 to scroll within the list box.

RESOLUTION
==========

Use one of the following methods to scroll through the list boxes rather than
using the universal scrolling feature:

- Scroll conventionally using the scroll bars.

- Use the Panning Anchor feature to scroll through the list box. To use the
  Panning Anchor with the Microsoft IntelliMouse, click the wheel button to
  display the Panning Anchor. Move the mouse up or down to scroll through the
  list box. Note that in Windows 98, this method may also cause the window to
  close unexpectedly.

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.

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

The Automatic Code Completion feature of Visual Basic automatically fills in
statements, properties, and arguments in the Code window. This feature displays
the possible code statements in a list box or a dialog box. You can access the
Complete Word list box by clicking Complete Word from the Edit menu while you
are in the Visual Basic Code Window. The Auto List Members list box is displayed
when you type an object name followed by a period in the code window. Note that
you can select the Auto List Members code setting when you choose Options from
Tools on the main menu, then click the Editor tab.

When you click the Complete Word or Auto List Members list box and attempt to
scroll by using the IntelliPoint software, such as by spinning the wheel button
of the Microsoft IntelliMouse, the list box displayed will unexpectedly close.

The next section demonstrated how to reproduce this behavior. The instructions
assume you are using the Microsoft IntelliMouse with the Microsoft IntelliPoint
2.2 software.

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

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

2. Double-click Form1 to display the Form1 code window.

3. From the Edit menu, click Complete Word to display the Complete Word list
  box.

4. Click on the Complete Word list box, and then spin the wheel button to scroll
  the list box. Note that the Complete Word list box closes.
