Hi,
I realize that this isn't totally on the subject of ua, but this problem
has taken up a lot of my past couple of days.  I was hoping that some
knowledgable fellow committee member might have some advice or
suggestions.

I've been working on a project to help blind chemists using web pages.
We're developing web pages which use javascript as part of the project.  
The web pages show up in explorer and netscape, but JAWS doesn't
seem to realize the pages are changing.  Is there something special
that needs to be done to get JAWS to work with javascript and browsers
oe have we stumbled across a JAWS bug?

Thanks very much,
Scott

Here are two test HTML files we've been using.
