Hope a positive mind.
Thanks.!
CS4 does open FH files a lot better than did CS2 or CS3. It would be good to have a way to actively seek out, view, and redefine the stuff that doesn't come through now, including substitute methods of accomplishing things (swatches made from tiled fills or lens fills; make opaque objects with separate solid strokes on upper layer/sublayer to replace FH's lens fills that are styled with solid strokes.
As a cartographer what I have most trouble with in translated files is type on curves - the sliders are exactly on top of each other and need to be dragged out along the curve - devilishly hard to grab the top handle, then you have to grab the bottom handles and drag them back again. Grr.
