I'm using Freehand MX 11.0.2 on my intel iMac running Snow Leopard. So far, whenever I've used Freehand with Rosetta, the scrolling has been reversed. I just could not get used to this.
To fix this problem. I just downloaded a freeware app called Scoll Reverser. http://pilotmoon.com/scrollreverser/
I put it in the applications folder, selected it and pressed command+i to bring up the get info window. Then I checked the "Open in 32-bit mode" box and the "Open with Rosetta" box. I run the app and it's reinverts the scrolling back to normal.
