Safari 2.0 now opens PDF documents inside the browser window. Previously, Safari would launch Preview (or another PDF reader like Acrobat if you preferred). It does not appear possible to force Safari 2.0 to revert to its previous behaviour, which I much prefer. Why? I really like Preview.app. You can get a table of contents or page thumbnails in the side drawer. You have the zoom in, zoom out, page up, page down and annotate buttons easily clickable in the toolbar. The search box is right there ready to go. Worst of all, some web sites (a lot of scientific journal fulltext gateways) open PDFs with a HTML frame on top. When you go to save the PDF using Safari's 'Save As' command, Safari gets confused and only offers you the choice of saving the page as a Web Archive or the Text Source. Basically, PDF searching, downloading and reading using Safari has taken a big step backwards. Is anyone aware of a way to reconfigure Safari 2.0 so that it will open PDFs directly in Preview.app (or Acrobat, or whatever) instead of opening them inside the somewhat crippled PDF viewer in Safari itself?
