The information in this article applies to:
 
 - Microsoft PowerPoint for Windows, version 4.0c
-------------------------------------------------------------------------
 
SYMPTOMS
========
 
During a slide presentation, a white strip may appear on blue shaded
backgrounds intermittently, especially if you move your mouse while a slide
is advancing.
 
CAUSE
=====
 
The problem only occurs with PowerPoint version 4.0c (not 4.0a) if you are
using a 256-color video driver and you move your mouse while the slide is
changing. The white stripe occurs where a certain shade of blue ought to
be.
 
WORKAROUND
==========
 
If you change the background color slightly, the problem will go away.
 
1. From the Format menu, choose Slide Background.
 
2. Choose Change Color.
 
3. Choose More Colors.
 
4. In the More Colors dialog box, change the value in the Hue box to 43300.
   Choose OK.
 
5. Choose Apply To All.
 
The slide should not change its appearance noticeably, but you will not get
the white stripe if you move your mouse while running the slide show.
 
STATUS
======
 
Microsoft is researching this problem and will post new information
here in the Microsoft Knowledge Base as it becomes available.
 
Steps to Reproduce Problem
--------------------------
 
1. Create a slide using the INTLS.PPT template. This template is in the
   <POWERPNT>\TEMPLATE\SLDSHOW subdirectory.
 
2. Make several copies of this slide.
 
3. Run the slide show.
 
4. Move the mouse as the slides advance. A white stripe will appear
   anywhere a particular shade of blue occurs.
