The testing page is available on my CFDeveloper site.
Second, if you can test a different browser/version, please also post your results.
My testing of Firefox 22.214.171.124, Internet Explorer 7.0.5730.11, and Opera 9.10. Since the current version of Netscape uses either IE or FF for rendering, I've skipped any testing of it.
I'd be very interested in documentation regarding this, so if you know more, please do post what you can share.
