[jawsscripts] Re: msaa and jaws

Hi Jeff,

I had not seen any responses to your question.  Did you get an answer yet?

I have downloaded old reference material from Microsoft.  I don't have any 
experience in writing JAWS scripts that depend on MSAA.  I get the feeling 
that JAWS itself is supposed to do most of the heavy work in this area. 
There are JAWS event functions to get called if MSAA changes status or sends 
alerts I believe.  I don't think they needed any special scripts to make 
iTunes work.  I am sure that they had to change / debug parts of their MSAA 
code to  make FS and Apple consistent in their interpretation of MSAA.
