I'm new to the Kobo world, having used a Kindle for several years. I bought a Glo HD to read public library books that are only available in ePub format. However, I'm having problems when I transfer a library book from Digital Editions to my Kobo. After ejecting the Kobo correctly from my Mac, I often get a DRM "not authorized" error when I try to open the book. If I do a reset (pushing the recessed button), the book will open without problem. So I assume this is some kind of database processing error that is fixed by the reset. One thing I have noticed is that if, after I eject the Kobo, I see a "processing content" message the book will open without having to reset. If I don't see that message, then I have to reset to open the book. I've tried ejecting when Digital Editions is open and when it is not, but that doesn't make a difference. One other thing is that the problem books always show up with a black cover on the home page, even though the cover png is in the thumbnail directory. The correct cover usually, but not always, shows up after a reset. I tried searching on the forum but didn't find anything particularly relevant.

So, my questions are:
1. How can I force the database to update without doing a reset?
2. Why are some of the covers still black even through the cover image is available?
3. What should I do differently to make sure the content is always processed after ejecting?

Further info: Kobo firmware 3.19.5761, Adobe Digital Editions 2.0.1 (I have the same problem on all versions of 3 and 4 as well)

Thanks for any help/insight you can give.
