Re: [orca-list] More on the orca not speaking thunderbird message content area

[Mike Gorse <mgorse alum wpi edu>]

Hi Michael,

This doesn't really solve the underlying problem, but I wonder if it would 
help to add a line like this into 
src/orca/scripts/apps/Thunderbird/script.py:

  app.setCacheMask (pyatspi.cache.NONE)

This should disable all caching.  There are several bit flags that can be 
specified (default is 
NAME|STATES|CHILDREN|ROLE|INTERFACES|PARENT|DESCRIPTION. 
pyatspi.cache.ALL caches everything.  With the newest git revision, there 
is a DEFAULT, which defaults to ALL minus ATTRIBUTES, which is also new).

Hth; I'll try to look more when I have some time.
