The information in this article applies to:

 - Microsoft PowerPoint versions 2.0, 2.0e, and 3.0

Summary:

An embedded or linked Micrografx Charisma Object in PowerPoint may
reduce the available resources in Windows every time the object is
redrawn on the screen. This occurs if you are using Micrografx
Charisma version 2.1 with file dates of July 22, 1992.

More Information:

An object is redrawn when you scroll, change the percentage view, or
move to a slide that contains that object (and the object is visible
on the screen).

Steps to Reproduce Problem
--------------------------

1. Install Micrografx Charisma 2.1 with file dates of July 22, 1992.

2. Open or switch to PowerPoint 3.0.

3. From the Edit menu, choose Insert and select Object. Then, select 
   the Charisma 2.1 drawing.

4. Create an image in Charisma 2.1 and then choose Exit And Return
   from the File Menu. Choose Yes when asked if you want to update
   the object.

5. Press ALT+TAB to switch to Program Manager and choose About from the 
   Help menu.

6. Make a note of the available system resources and choose the OK
   button.

7. Press ALT+TAB to switch back to PowerPoint 3.0.

8. Change the percentage view or scroll within PowerPoint to force
   a redraw of the embedded Charisma object.

9. Press ALT+TAB to Program Manager and choose About from the Help menu.

   Note that the available system resources are lower.

The amount of resource loss will vary depending on the number of
redraws that have taken place. You will typically see a loss of 2
percent for every three to four redraws.

Micrografx Charisma with file dates of July 22, 1992 is a "silent"
release of Charisma version 2.1. The original version of Charisma does
not exhibit this problem.

Micrografx has confirmed this to be a problem with the silent release
and will send an update disk that corrects this problem to customers
who request it. Micrografx technical support can be reached at (214)
234-2694.
