Hello Adrien and all,
In Hal 11 there is a toggle switch to prevent any action occurring should an
external application keystroke clash with Hal, it is Control/7 for just one
keystroke, and Control/8 to allow however many keystrokes required, should more
than one keystroke be needed, after which another Control/8 will reactivate
Hal.
Such a useful feature must still be there in Supernova 13, but might not have
the same Control option. This would effectively put Supernova to sleep, and can
be woken up immediately with another toggle press. Would this solve having to
continually have Supernova being activated and deactivated? Perhaps an enquiry
to Dolphin technical support will verify this.
Paul Benson.

Hi Michael
A couple of things, I use nvda as a portable package, I use
super nova for speech and not magnification. Yes I suppose
for me it's probably laziness or speed to just mute super
nova with ctrl 0 which turns the voice off, and launch nvda
and vice versa, I have created some batch files to quit one
and launch the other. Didn't realise about the hooks. That
must be the problem apart from trying to use 2 screen
readers at once. Thanks.
Adrien

Adrien,
The first part of your email said you quit Firefox and NVDA.
The second
part says you re-started Supernova and pressed control zero
to mute it
and NVDA 'shut off'. But you had already exited NVDA?
1. You shouldn't try to run two screen-readers at the same
time because
they use a technique called 'Hooks' to intercept Windows
messages which
are being sent to controls on the screen. If you have more
than one
screen reader running it creates a hook chain that can get
very messy
and each screen-reader can upset the other. Whichever
screen-reader is
loaded second will be at the start of the message hook chain
and will
intercept and maybe not pass-on the event messages to the
next
screen-reader.
2. You can silence Supernova by pressing control. Of
course that
doesn't mute it, but just shuts it up for it's current
utterance.
Are you using Supernova for it's magnification? I suspect
that might be
the case, but see the points in (1) above.
