I have had numerous issues with a folio for the Kindle Fire and have finally narrowed down the problem to this: The first 15 articles imported into the folio work fine but the 16th article, and it does not matter which article is the 16th imported only that it is the 16th total article to be imported, corrupts. This makes my folio unpublishable.
As for specs, I am publishing to a V.20 viewer in a multi-folio viewer. Every article works if it is imported before the 16th article.
Also, this issue is only for occurs on 1024x600 folios. 1024x768 folios function fine.
