Yes, a scrolling field is fine. But if you wanted to have a field (no
scroll bar) and other controls overlaid (or beside) the field and have
the whole thing scroll (as a group), then you could run into the pixel
Wouldn't you ? Or maybe I'm missing something.

I didn't say "no line wrapping". There are (I think) languages which can
be written vertically (e.g. Japanese, Korean), and in this case you get
a series of vertical lines - and a series of those vertical lines placed
adjacent to each other, requiring horizontal scroll to get through the
document (i.e. a complete transposition of English). So the pixel limit
night then be relevant for horizontal, just as it is for vertical.
But as you say - so long as you stick to scrolling the field, not
putting an unscrolled field into a scrolled group, you won't hit the
group pixel limit anyway.
And - since I can barely spell Unicode, far less understand all the
implications - I'll go back to being quiet now :-)
