Re: [orca-list] ff3 slow navigation response

[Joanmarie Diggs <joanmarie diggs gmail com>]

Scott recently improved the structural navigation speed through the use
of collections.  However to take advantage of this new functionality you
need both the very latest Orca from trunk as well as the very latest
at-spi.

Hope this helps!
