Looked through the tickets and did a search but could not find any info whether this is an issue for others or just me. When adding a book to calibre and converting it to ePub after launching it, there is no problem. However, when adding any more books to calibre after the first book, error windows show up while importing stating that each book is already present in the library with the same title and do you want to add it again (even though it wasn't previously in the library).
If you choose cancel, then the book previously added to the library is duplicated and the metadata is changed to that of the book I am trying to import. However, when converted, the actual ePub is the old book with metadata from the "new" book.
If you choose OK, then 2 entries appear in the library. Both have the metadata of the new book added, however, they differ in size and when converted to ePub and viewed, one is the new book and one is the old book imported first in the calibre session.

Eg:
Open calibre and add book 1 and convert to ePub = works
Then add book 2 and book 3, window opens saying book 2 and book 3 are already in library - 2 options cancel and OK
scenario A: choose cancel. book 2 and book 3 both added to library with metadata except when converted actual text is from book 1
scenario B: choose OK. 2 entries appear for both book 2 and book 3 with metadata except one copy of each book is actually book 1 with metadata from the new books.

technical data: mac os x 10.5.5 and calibre 4.137

btw. great program. donated to keep it going. thanks.
