If you set the movie to use AS2, either when you start a new movie or from the Publish Settings, then import your .ia file(s), the text will import as Classic Text. Then you can reset the Actionscript option in the Publish Settings and the text will remain as Classic.
There should be a real solution for this.
Oh I'd LOVE to disable TLF. I am seriously having to paste, select text, convert to classic - DOZENS of times per PAGE and thus HUNDREDS of times a day.
Very, very, very annoying and time consuming.
I've seriously considered downgrading to Flash CS4, haha.
I GUESS this is the best workaround I've found.
I've been having a heck of a time trying to find a way to bypass this thing, as TLF Mode completely screws up the bridging between Flash and AfterEffects.
So far nobody has come up with a solution, so I just assume there isn't.
I've been using CS3, and will probably stay there until Adobe gets their act together.
I resorted to converting to outlines in Illustrator to bypass this problem - it was just THAT annoying. I can't use Flash to do edits though, but still, much better than TLF.
