Malcolm,

If you turn off the scrollbar at the end the text will reflow and might end up a line or two shorter then the edt would hold, but you'd at least have one that was big enough.

>Well, that's a very, very clever solution. Thinking outloud: I can loop expand my editbox one line (determined by fontmetric) at a time until the scroll bar indicates its inactive. I will have to adjust the width of my editbox to account for the scrollbar which I will then remove when I'm done. All behind the cover of LockScreen = True, of course.
