Orca Tracking Issues, Other Qs About It

Hi:

Thanks for your interest in Orca.

Thanks for helping test Orca and for bringing issues to our attention.
It would probably be best if you brought these discussions to the
orca-list at gnome.org list:

  http://mail.gnome.org/mailman/listinfo/orca-list

In addition, if you could keep it to one problem per e-mail, it would
help everyone track the problems better.   Multiple unrelated problems
in the same e-mail message with a generic subject makes it really
difficult to track problems.

As a hint: really long messages containing lots of different questions
tend to sit in my inbox for a long time since I know they are going to
take a lot of time to respond to.  Short messages with specific points
and specific subjects tend to have the quickest turnaround.

When you say "tracking", are you referring to speech, magnification,
braille?  In addition, you need to be very specific about the app(s) you
are trying to use.  Some of them are not accessible.

I'm very puzzled.  Can you give more specific example(s) (in a new
thread on orca-list at gnome.org) of what you're doing and what's not
working?  These may seem like the same problem, but they're probably
different.

Again, I'm not really sure about what you're doing here.  I think you're
talking about the "Add to Panel" dialog you get when you select "Add to
Panel..." from the gnome-panel?  If so, there may be a bug in the
accessibility implementation of the icon view being presented by this
dialog and we should enter a bug against gnome-panel. Can you provide
specific steps to reproduce the problem (in a new thread on
orca-list at gnome.org)?

We definitely agree that customization is needed.  This is being worked
on: http://bugzilla.gnome.org/show_bug.cgi?id=354970

I've not seen the problem you are describing with Nautilus.  I need more
detail with what you are doing and the problems you are seeing.  In
addition, you might try using the list view in Nautilus.  You can enable
this by bringing up the Edit->Preferences dialog and selecting "List
View" in the "View new folders using:" combo box.

I'm not familiar with Rox Filer.  Where did you obtain it and how do you
run it?

I realize you are probably frustrated with Orca right now.  We want to
help.  I think we can work through these things, but we definitely need
more specific detail about problems that you are running into.  Without
this, both of us will be frustrated and we'll have trouble getting
anywhere.  ;-)

I don't think the GTK1 toolkit supports the accessibility infrastructure
(AT-SPI), so any assistive technology relying on the AT-SPI will not be
able to access it.  

There may be an alternative to XMMS, though.  I use my computer about
11hrs day for work only and get relatively little joy out of it, so I'm
the wrong person to ask about for entertainment and other diversions on
the machine.  ;-)  Other folks on the orca-list may be able to point you
to more accessible applications, though.

Yeah - something is very odd with gnome-panel on Ubuntu.  It seems to be
quite depressed and commits suicide frequently and without warning.  I
think the Ubuntu guys are taking it to therapy, though:

Orca is the default screen reader for GNOME.

It should do so as of GNOME 2.16 (and Ubuntu Edgy).  Is this not
happening for you?

I think keeping an eye on the Ubuntu updates would be the thing to do.  

Henrik, if you're keeping an eye on this thread - are you aware of the
gnome-panel crashing issue on Ubuntu.  If so, do you have any
information on it?

Hope this helps,

Will
