When does changing the 'Enable Access for Assistive devices' preference
actually take effect?
I am trying to cope with the APIs become usable/unusable whilst my app is
running and but have found that sometimes turning the preference off takes
effect straight away, and sometime it doesn't take effect until after I
re-login. (i.e. I can still use the APIs properly, even across relaunches of
my app)
I am assuming that they are always supposed to be in-sync with the
preference, but that doesn't seem to be the case.
FYI. I am not explicitly constantly calling AXAPIEnabled, I just let my code
try doing what I want and let it cope with kAXErrorAPIDisabled (obviously I
don't let it do anything if the APIs are not actually there (pre OS X 10.2)
Assuming that they are supposed to become unusable straight away, will my
app get any observer notifications of elements being destroyed?
A bit of a weird question I know, but I do like to try and see pitfalls
before letting my code out. :)
