On a new iMac that I have, it came with Preview 4.1. However, it displays things on the side bar quite differently than the older version that is on my Mac OS X laptop. For example, the sidebar display for one particular document on my OS X laptop has broken down very nicely by sections, a table of contents. However, that same document on the iMac with Preview 4.1 displays thumbnails of all 1459 pages rather than the same table of contents sections. And yes, even if I click "table of contents" on the bottom of the sidebar, that doesn't work. It just says "no sections". So the same document, but two different results. Has anybody found a work around for this? I looked through the preferences but couldn't find anything of use. I'm considering transferring Preview from my laptop to the new machine, but I'm having a hard time believing this newer version actually lost that nifty feature. Help is greatly appreciated. Thanks in advance.
