Hi Therese, I test with both JAWS and NVDA. When there is a button or object with an action both of these readers will read that to the user, either the button name or the HTML (button1234), with our current products.
I test with what development builds, so I haven’t made any modifications like those Darrel described. When you get the blank page have you tried checking for js errors in the console? (F12 to load). I’ll check here tomorrow to see if Darrel replied to your last post, and I’ll try to see if one of our developers may have something to add
