[orca-list] Pages with text that change dynamically

[Josà Vilmar EstÃcio de Souza <vilmar informal com br>]

Hi all.

Try to access the following url:
http://news.softpedia.com/news/Totem-3-6-2-Media-Player-Repairs-Ogg-Video-Streaming-302407.shtml

Note that after the page is loaded, orca starts reading texts at random.
This is in my opinion very annoying, especially if you are trying to 
read the entire document.

In the debug output of orca I found the following sequence:
----------> QUEUEING OBJECT:TEXT-CHANGED:DELETE:SYSTEM

Is there anything that can be done to avoid this noise?
Thanks.
