I'm looking for an application to replace Adobe Reader as a PDF Reader. The thing is, two weeks ago it started freezing, and I can't get used to this. For example, I have this book which has bookmarks for each chapter, but when I click, say, chapter 4, it freezes for about 5-10 seconds. And it gets very frustrating and annoying. The same thing for any other button I try clicking. I tried reinstalling it, but it didn't do the trick. I'm running 10.6.2 and I downloaded the application for 10.4.11 - 10.6.0 Intel, as it seemed to be the most recent version on Adobe's page. So can I do anything about it, or should I go for a replacement?
