  8.  *    These routines are 100% WinX compatible.  AES has a really hard    *
  9.  *    time keeping up with the correct redraw tables.  Unfortunately,    *
  10.  *    I have not yet put these routines in to counter its problem.    *
  11.  *    Wait for a later release for this problem to be cleared.        *
