You can avoid the problem by only using PDF files and delete all ePub files.
The problem only occurs when BOTH file types are on the PRS 900 AND one syncs with a PC or downloads from the Sony Reader Store AND also has bookmarks in the ePub files.
Since I deleted my PDF's and only use ePub files, I have no problems.
