Include Preview In Document By Default = NO
I just learned an extremely useful tip for iWork ‘08 preferences. In the General tab there is a single checkbox under the heading Preview. This checkbox would at first glance seem to control the ability to have iWork documents be QuickLook’able, but it’s the exact opposite. So long as that checkbox is checked you’ll have crappy Quick Look performance on iWork documents. So if this checkbox happens to be checked in your Pages, Numbers, and Keynote preferences then it’s in your favor to uncheck it as soon as possible. Enjoy, Alex.
