screenreader manual or automatically starting

[MICHAEL WEAVER <michaelweaver1 btinternet com>]

Hi!
I have noticed a possible inconsistency when I think Orca starts.
I have disabled the Login sounds so I only get the drums before I enter 
my user information.
However, the screenreader sometimes starts automatically and sometimes 
needs to be started manually even though I have noticed that 
accessability is enabled and that screenreader is checked which is strange.
I am wondering if this is a screenreader bug.
I also don't know which screenreader is being used exactly, I am trying 
to use Orca and when I do a manual run from a Gnome terminal and type 
orca, I presume it is Orca that is running.
There doesn't seem to be any welcome messages being spoken.
