I want to use Preview I really do. But I can't I'll tell you why. With Adobe Reader it AUTOMATICALLY centers and zooms in the pdf document I'm looking at. Preview does not unfortunately unless I'm wrong. Hopefully I am. I just like that about Adobe Reader 8.1. With Preview I have to manually do these things. Also is Firefox for the mac cocoa based? Is that the only real difference on firefox with camino. I prefer Camino by the way. Does Firefox slow down over time whereas Camino does not?? Thank you
