more on thunderbird accessibility review

[Krishnakant Mane]

hello all,
I have started to review accessibility of Thunderbird again.
As reported yesterday, I did start browsing the emails offline.
Now I have another problem which is known for quite some time.
Yesterday Thunderbird was opening very fast.
But today It has slowed down.
Infact I feel it should have speeded up because now since my inbox is 
off list it does not have to cache every thing at startup.
I have about 5000 mails in my inbox.
Now I get Orca's response about 2 minutes after I start thunderbird.
I have other folders such as archive_2011 which contains 15000 emails 
but I did not choose to download this folder.
Further I have 150 emails in my sent folder and it is  downloaded to the 
local machine just like my inbox.
Any suggestions or explanations?
Lastly, I try sending emails from tb during which I hear the to: field 
properly, but I don't here the cc: when I choose it from the dropdown.
I write an email address in to: then hit enter.
Now Orca should announce the current focus which is the dropdown for to: 
cc: etc.
But nothing is spoken.
I do a guess and press down arrow and then tab.
I type another email id in cc: and tab over to subject.
This time, while I shift + tab to cc: field, Orca not just announces cc: 
but also reads the email address present there.
Can some one reproduce this?
Is some work going on with tb accessibility?
happy hacking.
Krishnakant.
