First of all: I didn't find a Calibre bug/problem dedicated category, so I´m posting here and yes, I searched!

Hi everybody,
I´m adding a huge PDF library of scientific books to calibre in order to attach metadata and to organise the Jungle on my machine.

I´m running MacOsx 10.6.6 and Calibre.

Since a lot of the file are poorly optimize-scan, after addition to calibre I started to optimize some of that.
I'm running AdobePro9 scanned file optimization, OCR and files "size decrease" (Adobe magic stuff).

By the way, I found out that the iPad iOs 4.2.1 could visualize properly PDF until version 1.4 (Adobe v.5). After that the images are not displayed, irrespective to wich program I using to visualize it (I tested: iBook, Safari integrated pdf engine, Goodreader, iAnnotate).

After that process the file size is always different, but calibre does´n not refresh the metadata, so I try to cancel the format from the metadata (pointing to the actual file that is the new, small one) and to add it again.

After that it results in a Zero bytes file! I don't know where is the problem.

It happens exactly after clicking OK in the 'Edit Metadata Information' window.

I also try with other format (djvu), but the result is the same.

I guess that Calibre isn't happy to find a record in his db with the same name of an old, differing from the last saved file.

NOTE: If the file reside somewhere else on my machine, it's fine. Calibre creates a copy of that file in the right folder and Amen.
