Yoshiki,
One minor problem - it seems to break balloon help. All the balloons are
empty.
The problem is somewhere in to the GrafPort displayScanner methods. I
couldn't immediately figure out how to fix it without hurting the speed.
Reverting those two methods will fix the balloons, but make editing slow
again.
Oh, and I tried your change on a slow machine, and its a noticable
improvement for text editing of any size there, not just monster paragraphs.
Thanks again,
Eddie
