           CedFix - 1996 by Francesco Doro (fdoro at gpnet.it)


*** Introduction

  CygnusEd has a problem when it is opened on a CyberGraphics screen:  the
scrollbar makes strange effects on the cursor and one or more fake cursors
appear when text is scrolled with it.  It seems this happens with all
graphics boards except for CyberVision.  This small bug can be very
annoying and can discourage to use this amazing editor on a CyberGraphics
screen.  CedFix solves this problem.

  CedFix works with CygnusEd Professional v3.5c (the one included with the
magazine Amiga Computing 11/95); it should work also with version 3.5.  If
you don't use CED or CyberGraphics or you use another CED version or the
problem doesn't exists with your system you don't need CedFix.


*** Installation & usage

  Drag CedFix to the WBStartup drawer or copy the executable to C:  and add
to User-Startup a line like "C:CedFix".


*** Details

  CedFix patches the ScrollRaster function of graphics.library; before
calling the ScrollRaster, the patch calls a CED's routine that clears the
cursor.  After ScrollRaster finishes the CED's code is called again so the
cursor reappears.  When the text is scrolled with the scrollbar the cursor
is a bit flickering but the general effect is acceptable.  The patch checks
carefully whether the function is really called by CED but the overhead for
this check is almost null and so is the slowdown of the scroll.  If not
called by CED the patch does absolutely nothing so the ScrollRaster isn't
really modified; for this reason this fix can't work for other programs
that have similar problems.
