Preview does work in 0.9. (It wasn't available in 0.8.) It wants a proper encapsulated PostScript file, however, with the bounding box, and the "%%Page:" comments between every page, and various other details. It's through these comments that Preview can figure out where the page breaks are and how big of a window it should put up. If you give Preview a PS file without the above comments, it will ignore it. Yap, on the other hand, totally ignores the encapsulated PS comments. Thus it will dump all the pages of a multipage document on top of another. Someone posted a hack for 0.8 where the "showpage" operator was redefined in Yap to wait for a mouse down; this should still work in 0.9, however it bogs the system down and provides no way to go to the previous page or abort viewing. Yap also opens up a 8.5x11 page everytime, ignoring the size of the PS document. (You can resize the Yap output through the Page Layout panel.) I'd recommend trying to get all applications that generate PS to generate EPS. It's really not that difficult, and the benefits are great. And, one day, if (when?) printers start demanding EPS, those documents will be ready 8-). And of course Yap will still be useful for those cases when you want to sit down and try some PostScript hacking by hand...
