Hi roytravis, there was a firmware update a few days after the one you have loaded. Its called V2.01EN 2008-12-12 and its at:
http://www.jinke.com.cn/Compagesql/E...ice/update.asp.
It improves Mobi support, but I don't know if it affects bookmarks.
You can come and see me again and I'll do the update for you, if you'd prefer. I have the update file.
