Known Anomalies
===============
• During driver installation, choosing an installation path which 
  contains spaces can cause errors linking to helper files.  Users
  should use the default path, or use a path without spaces.
• When a constantly updating OpenGL application is running (such as the
  X29 or rollercoaster demos) screensavers run very slowly. This appears
  to be a problem with the priority allocated to the screensaver process.
• On a GLINT board, the OpenGL flying objects screen saver can 
  cause corruption of the desktop, this requires a re-boot to fix the
  problem.
• Microsoft Maze screen saver is never hardware accelerated
  due to a bug in the screen saver library code. An alternative
  customised 3Dlabs version is provided.
• Loss of 2D icons and icon corruption can occur when running OpenGL
  applications under Windows NT 4.0 without any service packs installed. 
  Please install Service Pack 3 to cure this problem.
