[orca-list] I see some interesting problem with Thunderbird

[Hammer Attila <hammera pickup hu>]

Hy,

In Thunderbird 3.1.5 version under Maverick I see some interesting problems:
Possible Mozilla Developers change the used GTK control with message 
list part. Now, if I see right, the GTK List control is used, prewious 
versions I think using GTK treeview or tree table control, I am not sure 
right control name. When I moving email messages with a folder, the 
speak child position feature spokening invalid position index.
For example, my Espeak filter folder have 267 messages, but the position 
index is not true spokened.
Anybody see this problem under Thunderbird 3.1.5 and Orca?

Another three interesting problems with related Thunderbird 3.1.5, this 
is I think biggest problems:
With my inbox have 1499 messages. When I select inbox folder name and 
press Tab key, Orca spokening the first focused message information 
about 22 second later. When I try move up or down arrow with this big 
inbox message list, I hear next message with 4-6 second later.
When I changing task and switch back Thunderbird, Orca spokening the 
application title, but I hear the focused message after 11-14 second later.
I newer see this type problem with Thunderbird 3.0.9. Perhaps this 
problems happened because Mozilla developers changed the message list 
control? Have an useful workaround to fix this issues?
I tryed Thunderbird 3.1.5 version under Maverick (this is the default 
awailable version), and I using Orca git master version.
If need, I opening a bugreport with this issue and attaching Orca debug 
output if possible do orca level fixes to fastest the list operations.
