the following might help. There is a next snap shot that is
meant to fix it but not sure if it is totally finished for the
the snap shot was created last night and can be found at
You can jump down by headings to where the next snap shots are
and there is a download link.
But if it is the same bug i have seen you will not be able to
use your browser to get it. may be a sighted friend can grab it
I am just downloading it now and will also drop box it for you
if you can not get it that way. It can be gotten from https://www.dropbox.com/s/a4nazm0q8te5ivg/nvda_snapshot_next-14952%2Cdd1cbe50.exe?dl=0
If you do the following in the email to get it you should get
it down. Locate the second link which is the drop box link with
the letter k for link in the email. Then you will need to use
the applications key on the link then arrow down to save link i
think it is then press the enter key. It will ask you to save it
some where save it some where easy to find like the desk top.
If you can not use nvda you might have to use narrator to
locate the link and do the same.
When the file is on the desk top or where ever you put it
locate the next snapshot file then press the enter key on it. It
should start up with the musical sound. there will be the
documentation screen tab to the check box and agree to it. It
should not have to be installed. Tab again then use the nvda key
+ letter N to get into the nvda preferences then arrow down to
tools a sub menu will come off it then locate the comms fixing
tool I forget what it is called. You will know it when you come
across it. Press the enter key on it it will then come up with a
message likeit had to do some thing to the registery i can not
remember the wording tab to the yes button then press the enter
key on it.
Sorry i can not help you after that. I am thinking it should
fix the problems you might have to do a reboot but not sure as i
have not used the tool which is actually a snap shot.
I will also put in the other way from off my website below.

Troubleshooting - NVDA says “unknown” or “pane” in all of your
browsers, Mozilla Thunderbird email client and other places
If for some reason you have problems with NVDA saying “unknown”
or “pane” check for the following symptoms:
In all of your browsers, or the Mozilla Thunderbird email
client, no matter what you do, you still hear “unknown” or
In the browser, email client and other menus you notice you
cannot get into your menus, or you are unable to use the quick
When you have been told the page is loaded and notice strange
Mozilla Thunderbird saying unknown while you try to navigate it
Your applications key does not work with it being spoken out and
other strange behaviour in Windows
The running applications icons are not being spoken out
It might be a good idea to do the following:
Please note: If you are hearing “unknown” or “pane” (as
discussed above) NVDA might seem like it is still working
properly but it may not be completely in Windows and other
You could try the following solution which will allow you to
re-register your dll files in case they are causing the problem.
Press the Windows key then type the following into the search
box. Type in “command prompt”. Once you have located command
prompt, in the search results, press the Applications key to
bring up the context menu. Arrow down to select “run as
administrator” and press the Enter key. This will take you to a
command prompt window. This will not be spoken out. You may need
sighted assistance for this.
Type in the following command
for %x in (c:\windows\system32\*.dll) do regsvr32 /s %x
This should re-register all components in the system32 folder.
When it is finished, you can close the command prompt window
with the Alt + F4 key. You should notice now where NVDA was
saying “unknown” as in some examples given, NVDA should now read
the icons in the running applications area of Windows, speak the
content of the webpage and menus, and also in Mozilla
Thunderbird and other places in Windows including the Windows
applications context menu.
hopefully one of the ways either the snap shot or this way will
hopefully fix it for you.
By the way if the latest snapshot fixes it can you let us know

I encounter a very strange problem on a machine where all
used to work fine.
It runs Windows 10 latest update and NVDA 2018.1.
In Mozilla apps, (thunderbird, Firefox) any object is
announced as "unknown".
More generally, in any app, conext menus are nomore spoken.
I triend to uninstall and reinstall NVDA, even deleting the
NVDA configuration directory, but it definitely does not work.
Has anyone encountered this and know how to fix it ?
