Hi Milan.
Is there a way to prevent this behavior, either in Orca or in theapplication?
I vote for doing it in Orca. :-) I guess we just never thought about the content being a XUL application. Oops!
I opened a bug and posted a patch here: http://bugzilla.gnome.org/show_bug.cgi?id=479848
Hope this helps! Take care. Joanie
