Re: [orca-list] Measures to reduce Orca and Gnome crashes

[José Vilmar Estácio de Souza <vilmar informal com br>]

Hi joanie.

To use the latest orca we need to update to a new version of ubuntu. 
What version is recommended? 11.04 or 11.10?
Thanks and congratulations for your nice job with orca.
I wish you all a happy new year.
