As promised, here is a short summary towards the TTF-bug which I depicted here 
lately:

  Most  of you meant, that the problem is caused by the font(s) itself,
  not meeting some TTF-specifications.
  However,  it  was in fact a memory problem caused by Windows' default
  settings! One of you (TNX Kevin!) had the answer:

  I  haven't  found  the  optimal  value (yet), but 50 does work (in my
  case).  However,  this  solution  is  no panacea: the machine becomes
  incredibly  sloooow  and the chars printed out are more "jagged" then
  before  (especially  visible  with  script like fonts in medium point
  sizes (~18pt)).

  Oh  yes,  a  last  note  applies: The problem seems to be well known,
  quite a lot of people wrote me having the same problem. Nevertheless,
  Microsoft  obviously  didn't  thought that it's necessary to document
  such  things:  neither in about 200K README-files nor ~1000 pages doc
  accompanying my Win 3.1, the above switch is documented!

Shame on you, MicroSoft!

TNX to everybody,
 Kai
