I have been working with CS6 auto-size text frames for 2 days and am already in love. They work so beautifully, but I can't get them to work on my master pages. Does anyone know if the auto-size works with a primary text flow box (wiht threaded text)? Master page text boxes (with threaded text)? I can't seem to find much information about this.
I'm pretty sure that that's not the way the Auto-size features was intended. It works when text is not threaded through them. It works well if you had a sidebar or a caption that might grow or contract when text was edited or added to it.
I see why you say that, but it actually DOES snap-to-content with threaded text and that is one of the best things about it (you could never do that before and, as a cookbook designer, I have much need for that function). But you are making me think that the threaded text boxes may not grow and contract automatically--instead you have to tell it each time to snap-to-content, which isn't quite the same thing. I see what you mean.
