I have this problem sometimes too: I'm not able to read a few lines of 
text in a Thunderbird message I'm composing when I use Jaws and the 
up/down-arrow keys.


My experience is that this usually happens when there's some sort of 
popup or dialog on the screen. For example, it used to happen when I'd 
add an attachment to my message. My guess is that there was something on 
the screen that indicated my message had an attachment and it blocked 
part of the text for Jaws. This no longer happens with attachments, but 
it still happens from time to time. For me, this problem is very old, 
but it happens much less often now than in the past.


I don't have this problem with NVDA, so if it's happening with Jaws and 
the message is important, I switched to NVDA.
