SUMMARY
=======

When you use the Matrox MGA video driver shipped with Windows NT version 3.5,
you may experience the following video performance and display problems:

- When you are working on a spreadsheet in Quattro Pro for Windows and you
  select a tab on the bottom of the screen to switch pages, the page you are on
  turns black.

- When you run Quattro Pro for Windows, the Mystify (32) screen saver runs
  slower than it normally does.

- When you start Quicken for windows version 3.0, the Twinkle Star bitmap is
  displayed one frame at a time with a ten second pause between frames.

CAUSE
=====

This problem occurs if you are configure the driver for high resolution
(1024x768) and 65,536 colors.

To work around this problem, set the video display for a lower resolution and
fewer colors.
