The SWF in the article were two snapshots that I overlayed, one from Flash, one from Word, so it has no interactivity with the curser.
Truth is, it's entirely possible to enable text selection, if that were a real demo of the text engine.
There's lots of other reasons not to use Flash, namely that its slow for lots of text, and it doesnt display anything at all on the iPhone and other mobile platforms. Using SIFR to replace headers is OK, but beyond that, I still hold that using Flash for text (on the web) is bad form.
In hindsight, I should have used the real deal.
