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.
