Re: Proposal: enable accessibility by default for GNOME

[Willie Walker <William Walker Sun COM>]

PS - Bug/RFE logged here:
http://bugzilla.gnome.org/show_bug.cgi?id=545849.  

If there are other specific problems that people know about, I really
encourage them to log bugs.  Otherwise, the team will likely not know
about them and they will likely go unfixed.  The current AT-SPI
maintainer, Li Yuan, is *very* good and is remarkable in his abilities
to diagnose and resolve problems.
