Re: [orca-list] my thoughts/decisions about orca

There's something going wrong with AT-SPI caching children. Either Mozilla 
is sometimes not sending children-changed events when objects are added or 
removed, or libatspi isn't properly updating its cache. I can't say which 
for sure--I haven't taken the time to track it down.

This patch to Orca should help in the meantime:
