Re: Proposal: enable accessibility by default for GNOME

[Willie Walker <William Walker Sun COM>]

Yowsa!  Li jumped on this one *fast* - there's already a fix and a 
release in place.  Way to go, Li!

This just makes me want to repeat the request to increase the 
communication regarding issues you have regarding the accessibility 
infrastructure.

For example, one of the recurring comments is "it slows my desktop down, 
so I turn it off."  If people can come up with specific test cases 
(e.g., "bring up window x of application y with and without a11y enabled 
-- notice the amount of time it takes it to appear"), it will really 
help focus the investigation.

We'll get there,  :-)
