Hi, Haridoss--
Yes, that is exactly the field that I filled in and expected JAWS to read, but I am finding, as you stated, that it will not.
Very disappointing since the Adobe accessibility web site recommends filling in the movie description:
Provide descriptions for movies and slides
Adobe Captivate allows you to easily provide text descriptions for your simulations. These descriptions provide details about the movie or slide to users of screen readers and other assistive technology.
Adding a description to an Adobe Captivate movie
Every movie created in Adobe Captivate should include a movie description. For demonstrations that are short or that rely heavily on the mouse and are thus irrelevant to screen reader users, the movie description alone will suffice. Longer movies should provide a description including a content overview and context for the user, along with individual slide descriptions where necessary. (The steps then describe how to add a movie description Edit -> Preferences -> Project -> Info -> Description.)
I'll just have to edit the published HTML and add my own description.
Thanks
