Hi Gregory,

Thanks for giving it a spin. I think I know the main problem. We are using
the HTML 5 labelling mechanism:

<label><input type=checkbox id=showA> Show As</label>
<label><input type=checkbox id=showB> Show Bs</label>

versus the standard:

<input type="checkbox" id="foo" />
<label for="foo">Show As</label>

So, either IE does not map the accessibility API properly or JAWS simply
does not handle this. I will send the example off to Freedom Scientific.
Freedom Scientific does not yet support HTML 5 in their products.

Subject:	testing the CanvasEditor attachment with JAWS12 and IE9 beta
            (was: Reworked Canvas 2D API using our revised DrawFocusRing)

aloha, rich!

using IE9 beta and JAWS 12 (latest official release) i can minimally
access the contents of


1. when i issue a ReadAll command, i hear: "Show As Show Bs";

2. when i tab navigate to the document via the IE9 chrome, i hear:
"Show As Show Bs";

3. when i tab navigate the document itself, i hear: "Show As" -- a
subsequent tab does not cause JAWS to announce the second item in
the canvas ("show Bs")

3A. if i tab navigate the document itself, whilst nothing is announced
when i tab a second time, a DownArrow causes JAWS to speak "Show Bs";

4. the checkboxes which the document source indicates should be included
in the canvas element are totally invisible to JAWS;

5. i could not determine if pressing the SPACEBAR while on 1 of the 2
checkboxes activated the checkbox;

6. i could not use JAWS' checkbox hot key (x) to access either

7. using the "List of Form Controls" command (INSERT+F5) i received a
list of two items:

check box not checked
check box not checked

but only the existence and state of the checkboxes are reported, not
their labels ("Show As" and "Show Bs"); when i attempted to select
one of the checkboxes using this mechanism, a recheck of the "list
of form controls" indicated that the checkbox remained unchecked

7A. i could not activate either checkbox using the "List of Form Controls"

let me know if you want/need more testing

hope this helps, gregory.
