Re: Is this a problem with ARIA implementation on authoring site or a problem with Jaws?

Oddly enough my Jaws 12 (12.00.167) with IE9 (I was silly enough to
leave my Windows UPdate on and IE was updated, either without me
knowing, or by me accidnetally clicking "ok" when prompted). Anyway,
this combination crashes instantly when I click the button to collapse
the control. I tried it twice, with same results. I suspect IE9/Jaws
combination is to blame and I see there is a Jaws update available
(1169).
So this may be something particular to my machine, but at least you
know there is a potential for user issues.
I will keep testing, NVDA/Firefox etc.
Thanks for the information y'all, this is very educational.
