Article: Q104104
Product(s): Microsoft Programming Utilities
Version(s): 4.0,4.01
Operating System(s): 
Keyword(s): kb16bitonly
Last Modified: 26-JUN-2001

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

- Microsoft CodeView for Windows, versions 4.0, 4.01 
-------------------------------------------------------------------------------

SYMPTOMS
========

The region on the Windows display where CodeView was active is displayed in
monochrome after CodeView is exited. The rest of the screen is displayed in
color.

CAUSE
=====

CodeView affects the Western Digital 90C30 graphic chip and causes the next
several paints done by Windows to be monochrome; that is, completely black and
white. This problem occurs with the standard VGA and the standard Super VGA
drivers that ship with Windows version 3.1.

RESOLUTION
==========

The colors on the screen can be restored by forcing a repaint in the problem
region. Try maximizing some application or try going to a full-screen MS-DOS
session under Windows.

Upgrading the video card BIOS may help prevent the problem.

STATUS
======

Microsoft has confirmed this to be a problem with CodeView for Windows version
4.0 and 4.01. The problem has been fixed in CodeView version 4.1 for Windows.
