Re: [orca-list] Problem with swing application not being refreshed to orca

[Michael Whapples <mwhapples aim com>]

Thanks for the suggestion, can certainly say I am leaving flat review 
(both through the flat review toggle key and also by alt+tabbing away 
from the application and back to it). Its always worth checking its not 
the simple thing at fault, I've had some of those catch me out before, 
unfortunately this time its harder than that.
