richview1.Clear;

richview1.AddFromNewLine etc.......

The problem seens to be that since the text isn't actually modified, but

cleared and reentered, therefore I have to use an integer to remember the

scrollbar pos.

The scrollbar disappears after .clear, reappears at top when the text is

recreated, then the scrollbar shifts down again, hence the flicker (and the

text "jumps").

Thanks
