Re: Orca orca crashing when braille is enabled

[Willie Walker <William Walker Sun COM>]

Hi Don:

I'm glad you looked into this and spoke up about it!

The short answer is that an incompatible change was made to the Python
bindings for BrlAPI sometime in the past 30 days or so.  I'll need to
modify Orca to work with this latest change.  If you want to fix this
one problem (there may be more - I'm not sure what all changed), you can
substitute the following for the "(everything)" parameter in question:

(0, brlapi.KEY_FLAGS_MASK | brlapi.KEY_TYPE_MASK | brlapi.KEY_CODE_MASK

Thanks for letting us know about this,

Will
