I've got an application that needs to put text in a window - wrapped n
word boundaries, and then allow the user to page back & forth through
the text.

Scroll bars are the obvious solution. But I don't see an easy way to
make them work "right". The problem is the word wrapping - I don't
know how many lines (or characters) will fit in the window until after
I've displayed it. Currently, I just display the text starting where I
left off, and then resize the scroll bar gadget after it's displayed.
This produces some interesting (and predictable) results.

I know there's gotta be a way to do this so the scroll bar works
correctly. Anyone got any suggestions? Or better yet, code?

	Thanx,
