Well NVDA works. Jaws don't. For me. I use Windows XP - perhaps you 
have another Windows version (I don't know what impacts the result)? My 
Jaws installment is fresh. I add a test page as attachment to this 
message, so you check if you get a different result.

I wanted to make the point that aria-hidden="true" is useful for 
progressive enhancement - aimed at AT users. And the fact that IE7 
doesn't implement ARIA is just another argument in favor of that view, 
sine it means that one cannot use display:none to hide a label if one 
wants to make the page compatible for Jaws+IE7 users.
