I've read that and, unfortunately, that blurb amounts to nothing. All that blurb says is that it's just as compatible as versions 8 & 9. Technically, it's easier to assign the 508-compatible information than it was previously.

"Compatible", however, does not necessary equate to "useable". In AS 2.0, it was a little more useable. The ability to force the reader to read in 2.0 may have been a fluke, but it was a darned useful one that I wish they hadn't (accidentally or otherwise) taken away.

However, if someone HAS figured out a reliable way to force a screenreader to refresh, or read targeted material, in AS 3.0, I would love to know about it.
