Marco, I'd appreciate it if you would post the following message to the
Amiga group on Usenet if that is possible.

   It seems to me that individuals associated with companies doing business
in the Amiga market are under a special obligation to provide accurate
information to the Amiga community.  The propagation of inaccurate
information about another company's product is foolish. It causes users
to question the technical competence of the originator and his employer.

   People have a lot of fun with disclaimers.  Here is a case where their
purpose is clear.  I note that there was none on this message.  Haitex
would be well advised to require them.

   This is of some consolation to me as I designed flicker fixer and much of
the discussion that I have seen on Usenet (I've only caught bits and
pieces) seems to be based on a misconception of the manner in which
it operates.

   I am not currently on Usenet. If people are interested in information
on flicker fixer I am quite active on most of the commercial services.
