  QEMM 7.01 caused some conflict here.  I can't tell you what feature of QEMM
  is was, but I went back to a working HIMEM/EMM386 setup and told 7.01 to
  Optimize that and though nothing seemed to change (ie same regions, stealth
  mode and memory free), the problem went away.

  So, if you get the above problem - check you memory manager first.

  This does appear to be a Word 6 problem (at least others also suspect Word
  more than Cirrus :)

  I'll repeat that 1.41 drivers work fine for me (for what it is worth).

  Guess what.  It was that same QEMM problem.  IDCHIP.EXE works perfectly now
  that QEMM has fixed itself :)

  The answer is yes...  I would like to thank all those who responded (including
  Cirrus support!).  Hopefully many of you can attribute the problems to memory
  managers or similar software/driver setups and get the conflicts resolved.

  I would like to express my satisfaction with the Cirrus based video card I
  have.  I saw a post which basicly said "Choose Diamond over Cirrus" to which
  I respond DON'T!  I pulled my Diamond 24X for the Cirrus because of major
  Diamond driver problems (even on the latest release) as well as timing
  problems in my 486.  As usual, the best card is what works for you, so take
  this with a grain of salt, but for the money a Cirrus card is hard to beat.

  Thanks again.

  David
