Re: Best way to hide headings from visual users while keeping them in the outline

Hi

Unlike other screen readers, NVDA does not hook into your display
drivers (well, this used to be the case, Windows 8 is changing that,
therefore causing a significant rewrite for a lot of assistive
technology vendors).
NVDA does not require admin privelleges.
I have never experienced NVDA causing any type of stability issues
(which is more than I can say for some other products).
I have run it on XP/Win 7 32 and 64-bit and Win 8, for over 3 years now.

A portable NVDA install can also be created easily, if you feel it is better.
In my experience, NVDA is perfectly save to install ona work machine
and I have never had issues, but of course I can never guarantee
anything like that 100% (nor can anyone), but I would be extremely
surprised if you saw any adverse effects, you would be the first that
I know.
NVDA does work optimally with Firefox, though it does work with IE and
Chrome (there are some smaller issues where some of NVDA's navigation
features or other internet-related functionality do not work 100% in
these combinations).
Cheers
