Hi Tracy:

This is terrific news. I am really glad that the fix was so simple.

Best regards,

Curtis Chong

Thanks guys.  I looked at the display settings, and my cursor shape was a
block.  I tried changing it to underscore, and the jumping problem is
solved.  Hooray!  
NFBCS members save the day, again!

Tracy,

I see Curtis has already mentioned this and you have responded, but make
sure that if your terminal emulator as a cursor shape and a curser blink
rate that the options are set the same as they are on the installation that
works.  Make sure you don't have any options turned on in your terminal
emulator that underlines or highlights the entire line or column containing
the cursur.  Make sure that the window is maximized.  Turn off any on-screen
keyboards or options that convert text strings like PF3/PF15 to action areas
or "hot spots" that can be clicked to execute.  I have no way of knowing
what your emulator might call these areas, but they can theoretically
confuse JAWS because sometimes the appearance within those area changes.  If
you have an option that moves your mouse pointer with your 3270 cursor. Try
turning that on if it is off or turning is off if it is on.  

If all of these emulator options are set so that both installations have the
same settings, go to the settings center and check the Caret and Cursor
options.  Depending upon your version of JAWS, you might find out a Caret
Time-out value, and making sure they are the same in both installations
might help, or just try increasing the value on the computer where you are
having a problem.  It looks like this parameter may have been dropped in
later versions of JAWS, though, so this parameter may not be present.  

Checking the horizontal and vertical caret definitions is also worth a look.
It is possible, though, that JAWS does not use these values with your
current emulator but I don't know how you can tell whether JAWS uses these
settings or not, so it probably makes sense to at least check these
settings.  You may need to load the JAWS settings for your emulator if you
have created separate settings.

Tracy, there are just so many things that could have an effect and those of
us replying may not think of something that turns out to be very obvious.
This might be a case where you need to spend some time with Freedom
Scientific technical support.  They may need to connect remotely to figure
out what is happening.  They may be able to see some kind of screen behavior
that might be responsible for this.  I hope you can get to the bottom of
this soon.

Best regards,

Steve Jacobson

I looked at my other session, and nothing looked different.  
This jumping is a real problem.  I can't figure out where I am, even with
the speech.  It seems like it's everything that's jumping, not just the
braille display.  If I use the Jaws key to check what character it's on,
that seems to be randomly changing as well.
It doesn't happen on every line, but, once it starts happening, it doesn't
stop for a bit.  Editing a line of code turns from a simple operation into
something that takes a couple minutes trying to figure out where I am.

Hi Tracy,

I'm familiar with Hummingbird. That's what my co-workers used. I think it's
also called Host Explorer but can't remember. I never used it because it
displayed all text as highlighted even when I tried modifying the JAWS
mainframe script to ignore dots 7 and 8. The Alva is an old device and I'm
surprised JAWS still support it. Let me know if you have more questions.

Thanks,
Dan

Hi Dan.  
I'm using Jaws, an Alva 640, and an emulator called Hostex or Hummingbird.
For some reason it has 2 names. 
All the same things work fine on a different mainframe, so, next time I get
in, I'm going to look at my profile settings on the one that's good and
compare to the one that's not so good.  If they're the same, it's back to
the drawing board.

Hi Tracy,

I was a mainframe programmer for 26 years and used JAWS with various Braille
displays. I can confirm what you reported. I have also seen instances where
JAWS ignored indentation. Don't expect any help from Freedom Scientific they
tried claiming that because the scripts were written by someone else Freedom
Scientific wasn't responsible for supporting them. I found this bogus
considering that the scripts are installed with JAWS. Ever since I have had
a bad taste in my mouth about Freedom Scientific and things have gotten
worse when I dealt with Braille hardware repairs.

If you can provide me more information, I will try and help. What version of
the mainframe operating system are you using? Which emulator and version?
What screenreaders and Braille displays are you using? How are you entering
text from the Braille display or a QWERTY keyboard? I hope this helps.

Thanks,
Dan

I'm editing a program within my terminal emulator, and, when I start typing
on a line, my braille display starts flipping quickly back and forth, too
quick to read or route the cursor.  It's quite distracting, and it makes it
hard to check where I am if I want to skip over a bunch of spaces to the
next spot I want on the line. 

I'm using the same emulator I've been using, but I'm in a different
mainframe than the one I know and love.  

It might be a TSO setting, but I'm not sure.  Any ideas?  Any more old
rascals like me, still programming on the mainframe?

Tracy
