Go to http://www.mozilla.org/access/dhtml/class/checkbox The role for the root document should be ROLE_APPLICATION, not ROLE_DOCUMENT.

There was a bug in the script. It appears to be working in my debug builds now but for some reason, not in official Firefox 1.5.

Still not working in Firefox 1.5.0.2

Appears to be a timing issues. It worked the first time when the image needed to be loaded, but not subsequent tries when the image was already cached.

This adds a small delay after domcontentloaded comes in, before creating an accessible for the document and using that accessible to fire an event. This also changes document load (reorder) events under ATK so they can be fired before the images are finished loading. That's what we've been doing for MSAA. Is the change okay?

What if the attribute is set dynamically after the page has loaded? Do you just not support that?

Hmm, this fix won't work for Firefox 2 (Gecko 1.8) because of the small API change in nsIAccessibleEvent.idl: + const unsigned long EVENT_INTERNAL_LOAD = 0xffff; We can't have API changes in Gecko 1.8. I supposed I could try to put the constant in an nsPI private interface.
