Just a quick tip for anyone having issues viewing PDFs on a Kindle 3. I noticed that some pages just went missing (were shown as blank on the Kindle) even though I could view them fine on my Mac. If you are having this issue, one way to fix it is using Mac’s Preview application. I found that just making a change – such as inserting an extra page then removing it again – and re-saving the PDF fixed the issue. No problems with PDFs on the Kindle now.
No idea why it works, it just does. May have something to do with this but I don’t have Adobe Acrobat on my Mac and the process seemed quite tedious (although it may not be, I have no idea) so I didn’t try it. Worth a try if you are on Windows I guess.
