Recently upgraded to 10.6 and I'm finding that Preview opens pdfs at an annoyingly high zoom level. I'd like to change the preferences so that every time I open a pdf it opens withone page fitting perfectly on my laptop screen. There doesn't seem to be a control for this in the preferences. I downloaded an app called "Pref Setter" so that I could get under the hood and change the default that controls this, but I can't tell which of the prefs I should be changing. Surprisingly, there doesn't seem to be anything specifically addressing this issue on the innertoobz. Anyone know how to do this? Thanks!
