Multiline TextField not wrapped correctly

Hi,
I am having a big problem with TextFields: I am instancing a TextField, embedding font correctly, assigning a TextFormat etc…, setting multiline as true, wordWrap as true, width to 200.
Now, when I insert a sentence about 3 times long as the set width (200) I just see the first third of the text, cut at 200 pixels, and the last word of the sentence in the second line, as if AS3 wrapped the last word only.

BLA BLA BLA BLA BLA BLA BL[COLOR=#d3d3d3]A BLA BLA BLA BLA BLA BLA BLA BLA BLA BLA BLA BLA BLA[/COLOR]
BLA.

If I set embedFont to false it works correctly: what the f***…?!
