No apology needed Stuart. You have done more than most and i would like
to take this opportunity to thank you on list.
I new the lo was not write but I now am pleased that someone from lo is
now agreeing with me. anyway moving on I will take a look at the link to
vote on the ticket to get accessibleIa2 added into the code for lo, let
me once again thank you for all your effort and hard work on this. OK we
don't have the result we would like but now we know we can maybe try and
get a fix for it.

> The Java Accessibility API is not as comprehensive as the IAccessible2 role mappings provided by IBM Lotus Symphony 3.0.1, but it is functional for the 3.4 and 3.5 releases of LibreOffice. And, for these versions Windows Assistive Technologies will work. For example, the Windows NVDA screen reader will function with cursor control and component announcements for the entire document tree.
> Windows versions of LibreOffice 3.6, including the current build 3.6.3 rc1, are NOT USEABLE with Assistive Technologies and they have not been usable with Windows Assistive Technologies at any point.
> For folks that I've mislead with my insistence that all is well with LibreOffice 3.6 and Java Access Bridge and JRE with use of Assistive Technologies like NVDA screen reader I was wrong--I apologize.
> I've updated the FDO#53474 (http: bug report https://bugs.freedesktop.org/show_bug.cgi?id=53474 ) and would encourage folks to vote, i.e. comment on, the enhancement to implement IAccessible2 API ( http://wiki.documentfoundation.org/Vote_for_Enhancement ) for Windows builds by incorporating the IBM contributed Symphony code base as a replacement of the Java Accessibility API as that is probably the fastest means of bringing Windows builds of LibreOffice to the same functional level as Linux builds that use the ATK AT-SPI accessibility APIs.
