Problem w/ createTextField wordWrap

This isn’t wrapping… it displays everything else fine…

this.createTextField(“caption”,1,100,310,260,75);
fmtEmphasis = new TextFormat();
fmtEmphasis.bold = true;
fmtEmphasis.multiline = true;
fmtEmphasis.wordWrap = true;
fmtEmphasis.size = 11;
fmtEmphasis.font = “Tahoma”;
caption.text = "The secret of a Stradivarius violin’s heavenly sound may actually have celestial origins. A tree-ring dating expert at the University of Tennessee and a climatologist at Columbia University offer a new theory.

caption.setTextFormat(fmtEmphasis);

I’m so clueless…arrgghh
