I am using a regular text box (not html) for large text fields. The starting size of the text box is small, and CanGrow is set to true. Most of the time, the text boxes grow correctly to fit the text. Occassionally I see the last line of text does not fit in the text box. In this case, the text is either omitted (missing) or, if the text box below is empty, the overflow appears in the text box below.
Sometimes by changing the justification, I can make the problem go away in a particular case, but I need a universal solution.
