[comp.sys.apple2] AWGS not deleting characters properly

sxaeg@acad3.fai.alaska.edu (greenwalt art e) (11/27/90)

  Very strange problem ocurring suddenly with my AWGS V1.1.
I'm using GS/OS 5.0.2 and have had no problems with either
like this since I first got my IIGS a couple years ago.
  Last night I entered the WP module and began to write a
letter.  When I made a typo I backspaced as usual but it
did not totally delete it.  It was as though it was off by
half a column in its positioning.  When I thought it looked
alright, I went out, saving the file, then came back in. In
looking at the "deleted" areas I found in some cases it
looked as though parts of one line had been superimposed on 
another.  I again tried deleting and this time it would
take parts of the words *after* the area being deleted as
well as parts of what I was trying to delete.
  Very confusing to say the least.
  I can think of nothing that might cause this as I have
added no CDA's or NDA's since last time I used it without
troubles.  The comm and db modules work fine as does the
graphic module.  And the WP module does everything else
fine.  It just suddenly doesn't delete properly.
  I'm on a ROM 01 IIGS with a 20 mg hard drive, 2.5 mg internal
RAM.
  Help!
