Hi kiwidude! Very recently discovered your plug-ins, and finding them a superb addition to Calibre's functionality. I'm having an odd problem with Book Sync that's popped up in the last couple of days. It worked just fine until then. I'm running the most current version of Calibre, the last update to Book Sync and Windows 7. Whether or not my Nook is connected, I can't get Book Sync to add a book to the sync list. When I select a book to add, the available selections in the drop-down used to be "Add to Sync List" and "View Sync List" (along with the Customize option). Now, all I see is "Remove from default sync list" and an unavailable option to "sync now" (again, with the Customize option). If I click on the "Remove" option, it gives me a message saying "No device identifier specified." Help! What am I doing wrong?

(BTW, I have tried closing Calibre, restarting the computer, and removing and reinstalling the plug-in, with no change to the function status.)
