PDFs move very "chunkily," i.e. never smoothly, on my iMac. I try to use the drag bar on the right and it does nothing--gives me the spinning wheel of death, the jumps several pages. When I use the button to advance one page at a time, it takes 4-6 seconds to respond. This is true regardless of whether I am using a 3-page PDF or a 500-page PDF (which, being in publishing, I do a lot). This is seriously disrupting my work.
I'm not even trying to edit, add or subtract anything from the documents, just flip through checking them.
How can I fix this?
I'm running an iMac 3.06 Ghz Intel Core 2 Duo, Lion OS 10.7.4. Upgrading from 4 GB RAM to 16 GB DDR3 Ram had no effect.
It's Acrobat 8.3.1. It is the only version that has been on this computer, but I may have migrated everything over from my previous computer, and don't recall if it had previous versions on it--possibly.
I my opinion, try downloading and installing the latest version of Adobe Reader (free) and check if you can read the PDFs properly. If that works fine, you can decide whether or not you need to upgrade to Acrobat 10 (paid).

Good call. It works fine with the latest Adobe Reader. Looks like it is a version issue, as you said.
Thanks a bunch. This has been driving me crazy for months. I thought about this issue, but asked a friend who's using the same versions, and she was having no problems. Go figure.
Good to know that Reader works.
When something is incompatible, it means that it may or may not work. Adobe Acrobat 8 was launched in November 2006 and Mac Lion somewhere in July 2011. You can expect a huge change in technology in 5 years. I wouldn't be surprised if Mac Lion doesn't understand what a software designed back in 2006, says. I guess, your friend is lucky enough to get it to work. I have seen issues where it simply crashes and causes other issues as well. Adobe strongly recommends the users to use only compatible version. In my opinion, there is no point of using an incompatible version and loosing the entire data.
