 My downloaded news content causes the reader to reset.

 This is a bug in the SONY firmware. The problem can be mitigated by switching the output format to EPUB
-in the configuration dialog. EPUB files typically only cause the reader to reset when clicking on certain
-links. Alternatively, you can use the LRF output format and use the SONY software to transfer the files to the reader. The SONY software pre-paginates the LRF file, thereby reducing the number of resets.
