Re: [orca-list] Live regions and XUL?

[Willie Walker <William Walker Sun COM>]

Hi Milan:

What I've discovered is that the text insertion events being delivered 
do not have the ":system" string appended, so we are ignoring them.  If 
I make the change attached to this message, I can make your test case 
speak, but I think I'd need to reread the ARIA specs and the Orca live 
region code to see if it is the right thing to do or not.  If you have 
time to do this, it would be awesome.
