Hi Dorene,
To this day, I have not found a Silverlight applet that is usable with JAWS. I tried several with JAWS 10, and was hoping that improvement would now be noticeable with JAWS 11.

On a related matter, Adobe AIR is one of the main competitors to Silverlight as a platform for rich media, browser-based applications. Adobe AIR has been inaccessible to all screen readers because of no accessibility API. Supposedly, the public beta of AIR 2 introduces MSAA support. Has anyone tried this recently?

Hi Jamal

Do you know any other Silverlight sites you could check? Any chance
the problem is site-specific and the developer just clobbered
something critical by accident?

FYI: I just tried the following Silverlight site with the latest versions of
three screen readers:

It seemed to work well with NVDA 2010.1, worked partially with Window-Eyes
7.2 public beta 1, and did not work at all with JAWS 11.0.756.

I thought one of the major feature enhancements of JAWS 11 is support for
UIA, the accessibility API that Silverlight uses instead of MSAA
(Silverlight controls are a subset of Windows Presentation Foundation, the
successor to Windows Forms in the .NET Framework).  Is some kind of manual
configuration needed to make the latest JAWS work with Silverlight?  I tried
both IE 7 and Firefox 3.6.
