[orca-list] A very difficult possible not always reproducable Orca Thunderbird issue

[Hammer Attila <hammera pickup hu>]

Dear List,

I see a very interesting Orca/Thunderbird issue under Orca 2.30.1 and 
Orca git master version, but I not found always working way to possible 
reproduce this problem and filling bug related this problem a valid 
debug.out:
Some time, when I writing a longer e-mail, and before the send I read 
the letter with up and down arrow keys because search have a mistaked 
line or need rewrite a text part, Orca not always reading correct actual 
line. Some time, usual half of the message, Orca reading actual line+1 
line (not the caret actual line) when I press down arrow key. Only help 
if I do press right arrow to search correct line beginning.

Anybody see this type problem and confirm? I using now Orca git master 
version, Ubuntu 10.04 and Thunderbird 3.0.4. For example, now Orca reads 
this e-mail correct with Up and Down arrow keys, this is a relative long 
e-mail. :-):-)
The difficulter think is not always happening this problem my system, 
so, this problem is not easy to debugging.

Attila
