SUMMARY
=======
When you use Microsoft PowerPoint on a Macintosh Powerbook 180c with video
mirroring turned on, changing the color scheme causes redraw problems on
both the internal and external displays, and causes PowerPoint to
unexpectedly quit or stop responding (hang).
In addition, when you move the gridlines (the guides) on a Macintosh
Powerbook 520c, the machine hangs.

MORE INFORMATION
================
Video mirroring is a feature of the Powerbook that allows two
monitors to simultaneously display the same information. Disabling
video mirroring allows PowerPoint to be used without problems on
this machine. To disable video mirroring:
1. From the Apple menu, choose Control Panels.
2. Open the Powerbook Display control panel.
3. Turn off the option for video mirroring.
4. Move the startup monitor and the menu bar to the external monitor by
   using the display control panel.
Video mirroring is disabled once the Powerbook is restarted.

Microsoft has confirmed this to be a problem in PowerPoint version 3.0 for
the Macintosh. This problem has been corrected in Microsoft PowerPoint
version 4.0 for the Macintosh.
