[orca-list] Orca stops speaking notifications: things I've discovered

[Nolan Darilek <nolan thewordnerd info>]

Reported this here a while back, but at the time it couldn't be easily 
replicated and I shelved it. Recently it began annoying me more, though, 
and I've tried digging into it. Essentially, after some amount of time, 
Orca stops speaking most notifications. I noticed that some still 
spoke--my wireless keyboard's batteries are low, and those always speak. 
But incoming mail notifications, drives inserted/removed, etc. don't 
speak until I reboot. Capturing a debug.out is difficult because I'd 
essentially need to leave logging running until I get a new message. But 
I did discover some things that might help track this down.


First, I discovered that clearing past notifications restores speaking 
of notifications. That made me wonder if the behavior had something to 
do with the notification stack.


I then pounced on the notification area immediately after a new email 
arrived and the notification didn't speak. On top, I noticed an alert 
about my low keyboard battery from 13 minutes ago. Right below, I found 
the incoming email from just now.


So if Orca gets an event for a new notification, is it just looking at 
the top of the stack and seeing an old/already processed notification, 
and not finding the newer one immediately below? That might explain away 
all of this, but I haven't had my coffee yet so take that for what it's 
worth.


Thanks.
